The History of Pop Rivets

The background of pop rivets started in t]he U.K. in the earliest 20th century. It was the British inventor Hamilton N. Wylie patented a method for installing tubular rivets from one side. Rather than the different method of pounding the metal shaft down while holding a buckboard against the back of the assembly.

Blind Rivets are the Superhero of Fasteners Industry. They got blind name because of its working nature, in blind rivet you don’t have to go through both side of any application. In other words if you can’t see the other side, then you can still join two Applications Easily. Blind Rivets Offers a Super Fastening capability and Used From Many Years. They Used in Almost Every Manufacturing Industry, Like

  • Aerospace Industry
  • Automotive Industry
  • Building Construction
  • Electrical Electronics Industry
  • Medical Instruments and Many More

Blind Rivets Commonly Known as POP Rivets. They Consists of Two Parts 1st is called Rivet and 2nd one called Mandrel. They can easily insert in any application with the use of riveting tools. The following things you have to taken into account before installing a blind rivet

As there was a need for a fastener that could be set from just one side of the workpiece aircraft designs changed from wood and metal to all-metal fabrication, during the 1920s.

Altogether, the two companies invented a rivet design with a mandrel (an object used as an aid for shaping a material head that would pop off after the rivet was set). The pop rivet, after the popping sound, heard when the rivet tool broke off mandrel head inside the shank.
Originally the rivet tool was designed by Wylie who was also adapted to set pop rivets. The tool consists of internal teeth that grabbed the long spindle, pulling it out and away from the rivet, while the head of the tool held the hollow rivet shaft in place against the workpiece. The two actions worked against each other to provide the tension that deforms and sets the blind side of the rivet.

Assembling a pop rivet required an operator to place the rivet into the tool by hand, then position the rivet into a pre-drilled hole before squeezing the handle to activate the tool. There are now advanced riveting systems that automatically feed the rivets—increasing production efficiency and gradually diminishing the chances of repetitive motion injuries in workers.


They have proven to be extremely popular because they are fast and easy to use and work well for joining thin sheet metal and composites.

The manufacture of pop rivets for use in aircraft increased to 3 billion during World War II, and, after the war, applications for pop rivets expanded to the automotive, appliance, and metal furniture markets. Dominant and Increasing growth for the company allowed it to build new, dedicated POP® rivet factories in the U.S., as well as in Australia and Japan, as post-war economies expanded.

What is Pop Rivets?

As it is said by famous personalities there is always a reason behind everything the name is synonymous with blind rivets: POP® was the original manufacturer of this innovative design. … Trusted by manufacturers worldwide, the POP® rivet range consists of a wide variety of high-quality fasteners that will meet the needs of your demanding manufacturing assembly process.

As the most revolutionary and world-famous – the POP® range contains the highest quality blind rivets and rivet nuts for non-structural applications for non-structural applications.

A POP Rivet is a blind fastener which can be inserted and set from one side of the workpiece. The POP Rivet is inserted into a pre-drilled hole in the materials you’re joining together.

Pop rivets are mainly utilized in a blind setting like blind rivets, but the material application is a little at variant. Pop rivets can be used with plastic, metal, and wood while offering a longer-lasting setting than traditional blind rivets developed outside of the lab of the George Tucker Eyelet Company.

Pop rivets from ITA Fasteners are evolved and high-end fasteners for modern assembly needs. They are used in the most challenging environments of demanding designs.  But Pop rivets are used for its most important functionality. Special tools are required to use pop rivets which cannot be used on regular rivets.

They are tubular fasteners that come with a mandrel through the middle. Rivets are inserted in the blind side, and a configuration tool is used to draw the mandrel through the body of the rivet.  It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.

What are Pop Rivets?

Believe it or not, “pop rivet” is typically just another name for a blind rivet. It started in 1934 when George Tucker Eyelet Company was approached by an aircraft manufacturer that needed help to develop a fastener that could be set from just one side of the material.

Whether  looking particularly for POP® rivets or any brand of blind rivets, chances are you’ll automatically search for “pop rivets.” Why? Because the term has become more than just a brand name, much like how Velcro or Kleenex are used to describe any brand in its product category.

However, a key differentiator is that POP® rivets manufactured by Stanley Engineered Fastening is manufactured in the U.S. When you’re looking for the highest quality fastener made from the best materials available, a fastener manufactured in the U.S. should be at the top of your list.

Project Applications for Rivets

Pop rivets can fasten wood, metals, and even plastic in a blind setting on a range of projects. At home, for an illustration, gutter construction often uses nails, which aren’t always an effective fastener due to the weight of water and other materials that can get stuck in the gutter.

• Joining a sign or nameplate to a wall, where one side is inaccessible
• Joining hinges, instead of using nails or screws
• In woodworking, because rivets provide a more sturdy construction than screws or nails

POP® brand rivets are often sought out by product designers for projects with unique, detailed specifications, especially when the project calls for consistency, quality, and integrity.

This product was later developed in aluminum and trademarked as the “POP” rivet. … Blind rivets are created from soft aluminum alloy, steel (including stainless steel), copper, and Monel.

Pop rivets are used in a blind setting like blind rivets, but the material application is a little different. Pop rivets can be used with plastic, metal and wood while offering a longer-lasting setting.

Although the name pop is widely used as a generic term for blind rivets, it just started out as a brand name for a particular style of rivet patented by the George Tucker Eyelet Company, which was acquired by the United Shoe Machinery Co. (USM). USM later became part of Stanley Engineered Fastener, which now owns the POP® trademark.

Over time, many more POP® brand products were engineered for specific applications, including:
• POPNut® threaded insert systems for providing load-bearing threads in single sheet materials (1982)
• POP® FSR (flush setting rivets) for the tight internal spaces inside electronics cabinets (2002)
• POP® Vgrip™ multi-grip rivets provide a wide grip range, permitting design flexibility and reduced rivet inventory for substantial cost savings in automotive production (2009)

Benefits of Pop Rivets

Although “pop” is often used as a generic term for blind fasteners and all pop rivets are blind (e.g., can be set from the outside), not all blind rivets are POP® brand rivets.

The highest quality manufacturer of POP® rivets which are made by Stanley Engineered Fasteners are now the only U.S. manufactured blind rivets. Design engineers seek out the top brand when looking for consistency, as well as high quality and integrity of the fastener.

Typically, product designers who specify pop rivets are looking for a unique, engineered type. For an illustration, in case of applications where the head of the rivet will be visible (such as in aircraft).

Additionally, POP® brand fasteners offer a complete design-to-end use assembly approach with support from a network of distributors and in-house engineers/product specialists.

What Is A Blind Rivet?

Blind rivets, also commonly referred to as POP Rivets, are mainly used in applications where there is no access to the rear (blind side) of the joint. Rivets have a two-piece construction; one is called the rivet body, shell, or hat and another is called the stem or mandrel. A benefit of blind rivets is that they are not material specific meaning they can combine two different material types together the same way.

To use a blind rivet, a hole is drilled then the rivet is seated inside of the hole. Then a tool pulls the mandrel against the hat of the rivet.

One of the biggest benefits if rivets are that there is no way to over or under-torque a rivet.

Installing a Blind Rivet

Before rivet installation can occur, several things must be taken into account.

Materials The softness/hardness of the materials may be enough to change grip range or head style during installation.

Rivet Material The rivet material must be chosen based on environmental factors, strength, corrosion resistance, and installation materials.

Head Type There are several different head styles covered later in this article.

Rivet Length The length of the rivet will change the grip range.

Rivet Diameter The rivet diameter determines the size hole that needs to be drilled.

Grip Range A rivet’s grip range is the range of how thick the material can be for a proper installation.

Installing a blind rivet is a simple and extremely fast process which is what gives POP rivets their excellent reputation. Whereas Installing them requires only the few simple steps listed below.

1. Drill a hole into the materials.
2. Choose a place the rivet into the two materials.
3. Place the Rivet Installation Tool on the mandrel of the rivet.
4. Activate the tool (usually by some lever or trigger mechanism) to pull the mandrel towards the surface.

When the mandrel gets tight in the material it will snap off at a predetermined point leaving the hat with a portion of the mandrel stuck inside.

How to Measure a Rivet

1. Measure the diameter of the rivet itself with a dial caliper or a measuring gauge.

2. Measure the underside of the rivet head to the end of the rivet head. *Don’t Measure the mandrel. The hat length it what you are looking for.

3. The grip range of the rivet will be shorter than the measured length. The measured length will be 1.5x the rivet’s grip range (including the ball at the end of the rivet).

EXAMPLE: If the length of the hat is 1/2″ the rivet has a 3/8″ grip (.375), also known as a 4-6 rivet. Please refer to the diagram and charts below for grip ranges

• Mandrel – Long end that is broken off the rivet during installation

• Hat – Portion of the rivet that is inserted and expanded to fit a hole

Pop riveting is a technique that is used to join thin pieces of metal and it can also be used to join plastic sheet. The rivet has two parts; the pin and the rivet.

Pop riveting is a technique that is used to join thin pieces of metal and it can also be used to join plastic sheet. The rivet has two parts; the pin and the rivet.

This technique is used where the metal or plastic is thin and where the joint does not have to be very strong. It is ideal for joining aluminium or even thin sheet plastic.

7 Best Uses for Blind Rivets

Blind rivets or pop rivets, are cylindrical nail-like fasteners with a mandrel. Unlike other types of rivets, these rivets can be used to fasten wooden or plastic materials aside from metal. Pop rivets can fasten metals, wood, and plastic even if there is no access to the back part of the material.

1. Building or Home Applications

Blind rivets can be used for different purposes at home. Many homes make use of gutters to lead rainwater down a drain. In gutter construction, nails may not be able to provide effective fastening. Other building or home applications that may require the use of rivets include installation of wind guards, hanger straps, window blinds and many more.

2. Attaching Nameplates and Signs

Nameplates and signs can be seen almost anywhere. Attaching nameplates or signs to a wall can be done in many ways. In cases where there is only access to one side of a structure, blind rivets can be used as fasteners instead.

3. Fastening Wall or Ceiling Decorations

Some types of wall decorations require a strong fastener for support. Framed pictures and framed paintings may easily fall off a wall without proper support.

4. Attaching Hinges

Hinges are used to attach doors, windows, appliances, shelves, and more. In order to attach the hinges to a wall, or a surface, one needs to use screws or nails. Instead of screws, some people make use of blind rivets as a replacement. Some hinges also come with rivets instead of screws.

5. Attaching Door Knobs, Drawer Pulls, and Handles

Drawers need drawer pulls, doors need knobs, and other pieces of furniture or equipment need handles. These objects can be attached using nails screws or rivets. In places where nails and screws are not applicable, rivets can be used instead.

6. Woodworking Applications

Rivets may also be used in many types of woodworking projects. Cabinets, shelves, lockers, wooden stands may require the use of rivets. Rivets provide secure fastening and are more durable than common nails and screws. Wood workers need to ensure that their finished products are sturdy.

7. Industrial Applications

Manufacturers of boats, aircraft, and other vehicles make use of blind rivets most of the time. In aircraft manufacturing, there are a lot of instances where only one side of a metal piece is accessible.

The pop rivet was invented in Scotland shortly before World War I. In the United States, inventors such as Carl Cherry and Lou Huck experimented with other techniques for expanding solid rivets, such as the pull-through method.

White, Brown and Black Pop Rivets are all Aluminium with Painted head’s.

The larger surface area created by the large flange prevents pull through by distributing the force evenly.

History of Rivets & 20 Facts You Might Not Know

The term rivet is used to describe a variety of fasteners with a couple of common traits. They are pre-shaped at one end and have their other end reshaped when they are put to use. All have a smooth shaft that passes through the materials being bonded. Riveting is used in all types of construction today, metal is the most commonly riveted material. But wood, clay, and even fabric can also be riveted.

The best known type of rivet, the hot rivet, provides the strongest joints. In this process, glowing hot rivets are fed through precisely-drilled holes where the unformed end is hammered to close the joint.

The story of the rivet is a fascinating trip through history. Here are 20 facts about rivets you may not know:

The first rivets appeared in Ancient Egypt over 5,000 years ago, where they fixed handles to clay jars.

By the time of the Ancient Romans, rivets were commonplace in construction.

Seventh-century Vikings used rivets to attach the planks of their longboats.

By the mid-19th century, advances in metal technology signaled the dawn of the modern riveting era.

Wrought iron, steel, and aluminum are the most common riveted metals because of their relatively soft composition.

Cast iron is impossible to rivet because it is so inflexible.

Bolts and welding are two other ways to attach metal together, and each has its use. Bolts are more versatile because they can be disassembled. Welding is more efficient, lighter, and versatile because it can attach a variety of shapes in many configurations. The downside to welding is that it affects the cellular structure of the metals being joined, and can create unwanted internal stress. Riveted joints are more flexible and give under changes in temperature.

The first common, modern application of the rivet was in boiler making.

The ship-building industry owes much of its early success to the process of riveting. Huge increases in maritime traffic between 1830 and 1940 boosted the use of the rivet.

There are two types of riveting: hot and cold. Cold riveting is used most often when small rivets are required. Hot rivets are typically larger, and used in large-scale construction like ships, boilers, and steam engines. These rivets are heated red-hot before installation.

By the mid-1800s rivets were being used in the construction of architectural buildings. Iron beams were riveted together, creating super-strong structures and paving the way for the skyscrapers of today.

Art and architecture utilized the rivet nearly as much as industry did. At the time of its construction in 1887, the Eiffel Tower in Paris was the tallest structure in the world. At 1,063 feet tall, the tower was formed by 18,038 pieces riveted together with 2.5 million rivets.

Other notable uses of rivets throughout history include the Golden Gate Bridge (1.2 million rivets), the Sydney Harbor Bridge (6 million rivets), and the RMS Titanic (3 million rivets).

On May 20, 1873, Levi Strauss secured a patent for his denim jeans with copper rivets. The rivets were meant to reinforce the pants at common stress points. To date, Levis has sold more than 200 million pairs of copper-riveted jeans.

Many World War II era tanks were riveted together, until weaknesses were found in that method of construction. Evidence from the field of battle demonstrated that the rivets could come loose if a large projectile hit the tank. The loose rivets would become small projectiles themselves, careening around inside the tank and causing injury to the soldiers.

Some drummers use special sizzle cymbals, which differ from regular cymbals in that they have several rivets attached to them. When struck, a sizzle cymbal’s sound is louder and sharper.

Ancient techniques for installing rivets utilized a hammer struck against a specialized tool called a bouterolle. This cup-shaped tool would help form the hammered end of the rivet into a mushroom-shape identical to the other end.

The advent of pneumatic tools made riveting more efficient. Today’s riveting process is done with special air-powered riveting guns that fire many times a second, hammering the rivet head into its final, mushroom shape.

Pop rivets are also known as blind rivets because one person can easily install them. Instead of hammering the rivet, a special riveting tool pulls the inside section flat.

The word “rivet” has its origins in Middle English and Old French, from the word “river” which meant to fix or clinch something.

The pop rivet was invented in Scotland shortly before World War I.

Overall, pop rivets are popular and reliable because they install quickly and easily, producing strong and reliable fastenings.


No matter what industry you are working in, the time is going to come that you need to grab for a handful of specialised fasteners in order to get the job done. There are many types of fasteners in the world and they range in terms of size, quality, and material fabrication.

Blind Rivets vs. Pop Rivets

Talk to anyone who has had to work with tools and they’ll eventually come up with a horror story about not having the right tools or fasteners by their side.

1) What Are Blind Rivets?

Blind rivets are a type of fastener that can be installed into hard-to-reach places with relative ease. Blind rivets come in a variety of different materials with stainless steel and aluminium being the most popular.

Blind rivets are now used to assemble everything from Blind rivets come in a variety of sizes, styles, and materials.small electronic components in cell phones to steel beams in the world’s largest bridges.

How they work

A blind rivet has a smooth, hollow, cylindrical body topped by a flared head and a solid-rod mandrel with a bulbed head that extends from the hollow rivet shaft. It looks somewhat like a nail. The mandrel head expands the walls of the rivet outward, pressing them firmly into the walls of the hole while forming a tightly clinched load-bearing area on the opposite side of the material.

Rivet manufacturers put grooves on some mandrels to weaken them, in essence predetermining the spot where tension will break them.

Controlled expansion of the rivet body is accomplished through proper design and material selection. This, in turn, lets blind rivets join a variety of dissimilar materials, including metals, plastics, and woods.

Designers select blind rivets based on the specific applications, and mandrels for how they perform as a built-in tool. The goal is to have rivet bodies deform as specified, and mandrels to break at precise loads to ensure joint consistency, strength, and durability.

Benefits of blind rivets

Blind rivets are the fastest way to join materials. They can be set at 150 to 500/hr, and each setting is identical. This cuts assembly time and costs. Unlike threaded fasteners, there are no concerns over tool clearance, rotation failures, and secondary parts such as bolts and tapping plates, all of which add assembly time, weight, and cost. (Tapping plates are flat parts fastened atop the workpiece to reinforce the threaded parts installed in thin materials.)

Breakstems also work in ductile materials and thin gauge metals. If necessary, rivets with large heads (at least 50% larger than the hole) can be used to spread the load further. As a rule, mandrel heads must be big enough to spread the load but not so large as to waste material and add unnecessary weight.

Compressing the rivet body during installation compensates for such irregularities, as do metal legs that expand the load bearing surface.

Breakstems can fasten painted parts, as well as those with other finishes without causing surface blemishes. Thread and bolt fasteners, on the other hand, can scratch, dent, and dimple surfaces.

Types of blind fasteners

Blind Fasteners comes in two types of open-end and closed-end.

Open-end break stems are the most common. The mandrel breaks near the blind-side head and has flanges or countersunk heads for use in thin-gauge metals and low-strength materials.

Closed-end break stems seal holes by closing the tail end of the rivet body and capturing the mandrel inside the rivet bore. They are not used as extensively as they once were, having been replaced by open-end versions that seal the rivet body with equal effectiveness.

Selecting and installing the right blind rivet in the right hole involves rivet diameters, grip ranges, hole preparation, head style, and corrosion resistance.

Rivet diameter: Blind rivets are available in diameters from 3/32 to ¼-in., with 1/32-in. incremental increases available. The larger the diameter, the higher the shear and tensile strength, which is due to the thickness and material of the rivet body.

Hole preparation: The rivet must completely fill the hole. Principal factors that ensure this are material thickness, grip range, and rivet diameter.Otherwise, no special preparation is required as long as holes are free of excessive burrs.

Head styles: There are three basic blind-rivet head styles: protruding, large flange, and countersunk. Protruding heads (also called dome or button heads) are the most common and simplest.Countersunk heads, after installation, are flush with the material. They are used for a better surface appearance or to reduce wind drag, such as in assembling aircraft.

Corrosion resistance: To slow or prevent corrosion, rivet bodies and mandrels are often made from identical materials, including low-carbon and stainless steels, and nickel-copper and aluminum alloys. Stainless steel breakstems offer the best corrosion protection in environments such as swimming pool ladders and city buses exposed to salt.

Grip range: The materials being joined must have a thickness that falls within a fastener’s grip range. While a grip range is an allowable difference between rivet length and material thickness.  A 0.5-in. grip range is usually the maximum length attained by standard break stems, but custom designs can stretch this to an inch.

The various types of blind-rivet installation tools, which includes handheld, lightweight, and semiautomated.

Handheld tools install fasteners with lower break loads, typically 1,000 lb or less.  Hydropneumatic hand tools are most commonly used to install blind rivets.

Up to the mid-1980s, most hand tools were steel and weighed a hefty 15 lb or more. Modern versions are lighter and more powerful.

Multiheaded semi and fully automatic workstations can install up to 268 break stem simultaneously.

Open End Open End Rivets are the most popular rivet variety available. They rely on the balled end of the mandrel going into the hat forcing it to expand.
Closed Ends Closed End Rivets are used for applications where the installed rivet will be exposed to liquids or vapors. The sealed end prevents liquids from going through the rivet into the installation or speeding up the corrosion process.
Multi-Grip Multi grip rivets have a significantly wider grip range than standard POP rivets. They are commonly used to substitute conventional rivets where the material thickness varies.
Tri-Fold (Exploding) Tri Fold or exploding rivets have a wider grip range due to the way the hat bulges. They also resist pull-though by having three folds distribute the pressure over a wider surface area.
Interlock (Structural) The mandrel locking mechanism on these rivets create a stronger assembly than other types. This type is recommended for structural applications.
Painted Head Painted rivet hats to match your applications to leave a blended less noticeable rivet in its place.

Head Styles

Dome The dome head sits rounded and exposed when finished.
Large Flange Large Flange rivets have a wider hat to better distribute surface pressure and prevent pull-through.
Shave Head The mandrel snaps further up on these rivers requiring a cutting and filing tool to shave them down to a clean finished look. They are exceptionally popular as trailer rivet replacements.
Countersunk A Countersunk head sits almost flush with the surface when installed.
Low Profile (Flat Head) These heads are almost the same as a countersunk but sit up slightly higher.

Materials The softness/hardness of the materials may be enough to change grip range or head style during installation. Rivets come in either all one material or material/material options.
Rivet Material The rivet material must be chosen based on environmental factors, strength, corrosion resistance and installation materials.
Head Type There are several different head styles covered later in this article.
Rivet Length The length of the rivet will change the grip range.
Rivet Diameter The rivet diameter determines the size hole that needs to be drilled.
Grip Range A rivet’s grip range is the range of how thick the material can be for a proper installation.
