Dome Bolts

Dome Bolts

Dome nuts mainly known Acorn nuts due to the head shape is alike to acorn.  It also comes under the name of Crown nut, Blind nut, and Dome cap nut. The nut is made in one piece along with a cap at one end and is normally made available in steel, stainless steel, Nylon, and brass.

When it was invented ?

By a lot of careful thought about some screw thread which was invented in about 400BC by Archytas of Tarentum (428 BC – 350 BC). Archytas is sometimes named as the creator of mechanics and was an existent of Plato.

Why are dome head bolts used?

They are also called as mushroom head bolts or dome head bolts. They are utilized to fasten wood to wood, instead of metal to wood.

What is a dome nut used for?

Dome nuts consist of numerous varieties of uses. From being used for its aesthetics as a cover for threaded rods and as caps for machine screws in architectural metalwork. To be utilized in the car modification business as an alternative to manufacturer-supplied nuts and fixings.

Description: Hex dome nuts or acorn nuts got their names due to the dome-shaped projection on one side of the nut. The external threads of the screws inserted into these nuts are securely surrounded within the dome. In addition to the protection it offers, these nuts provide the structure of an aesthetically pleasing look.

Dome Head

Stainless Steel Dome head bolts also named as button heads or mushroom heads these are smooth, stylish and gives a fresh finish and are one of our best sellers. A must in any workshop these are commonly used as screen bolts, fairing bolts, mudguard bolts, number plate bolts, chain guard bolts, heat shield bolts to name just a few. Produced with rolled threads which enhances sheer strength and gives a smooth fitment, then polished to a mirror finish these corrosion-free bolts which make the most of any bodywork.


Hex dome nuts or acorn nuts got their names because of the dome-shaped estimate on one side of the nut. Which is widely utilized to protect objects close to the ends of screws from scratches and structural injuries. It, in addition, decreases the consequences of physical mishaps on human skin if it somehow strictly hits the fasteners. The external threads of the screws inserted into these nuts are greatly encompassed within the dome. In an exertion to the defense it provides, these nuts provide the structure of an aesthetically pleasing look.

It is obtainable in stainless steel, carbon steel, and alloy steel to carry more wear and tear while also making it more corrosion proof. The dome nuts are approached in different sizes, ensuring you use them on screws with any length. By non-payment, the size of the nut is ‘small’ which refers that it is utilized for shorter screws.

Insert Nut

Insert Nut

This provides a threaded socket for a wooden workpiece, just as similar to a wall anchor. These are located into a pre-drilled hole by one of two means: screw-in and hammer in.  Which are advantageous over T-nuts and barrel nuts, due to they can be installed from one side of the workpiece.

Screw-in type

Mainly these types of insert nuts possess an external thread and hex head and are screwed in with a Flat Blade Screwdriver or an Allen wrench. The screw-in insert nuts come in multiple sizes and take different screw sizes. Take an example, of a “1/4-20” insert nut, will take a 1/4-20 inch bolt. The pre-drilled hole must be as intense as the length of the insert nut plus any portion of the bolt that may be screwed past the end of the nut in the workpiece.

Hammer-in type

This type of insert nuts, usually known as knock-in nuts, are lined with barbs and are hammered in. They are generally assembled of steel, brass or nylon. They are constructed to work in wood and particleboard.

Not all nuts attribute a traditional hexagonal shape. Whereas hexagonal nuts are popular because they are easier to turn — and therefore to install — than other shapes, but that doesn’t mean all nuts are hexagonal. Insert nuts, by taking an example, feature a cylindrical shape with exterior threading. In the below-shown image to the left, they share little or no resemblance to hexagonal nuts.

Blind Rivets

Blind Rivets

Over 3000 BC rivets have been around. Where they, first of all, they appeared in Egypt, where wooden rivets were utilized to produce a variety of tools.

Sometimes after that, the wooden rivets were used as fasteners in Gaul (France) while it was under the instructions of the Roman Empire.

Whereas in the 7th and 8th centuries the Vikings installed planking on their boats using wooden rivets.

From 1840-1930 the use of rivets evolved, and so did the materials that could be fastened. Wooden constructions were widely used and joined with rivets, but the large thickness of parts being fastened resulted in structural disadvantages: for example the risk of rivets splitting made structures unreliable.

During the start of the 19th century, there was a breakthrough in the iron and steel industry which helped overcome the unreliability of wooden rivets. Wrought iron and steel, with their ductile behavior.

Ductile behavior means the ability to deform iron and steel to produce metal rivets.

A number of other methods have surfaced since then. However, rivets are still commonly used today to fasten materials together.

Blind rivets, also usually referred to as POP Rivets, are mainly used in applications where there is no access to the rear (blindside) of the joint.

Rivet pin

The pin is the main body of the rivet which will slot through the pieces of material being joined together.


The rivet head acts as a stopper on one side of the fixed materials.

The head will sit on the outside of the material to stop the rivet from sliding out of the material.

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.

The Background of Bolts

Over 200 BCE, Archimedes invented a large bolt or screw pump, making use of the screw principle. The pump contained a screw with helical threads sculptured on a shaft, fitted inside a tube. It changed radically the irrigation, allowing water to be raised from low-lying water bodies. While Archimedes is renowned with this invention, historical evidence suggests that he actually borrowed the idea from the Egyptians, who he saw using wooden screw pumps for irrigation.

Modern bolts came into existence much later, in the 15th century. This occurred when a German publisher, named Johann Gutenberg, used bolts to fasten his printing presses.  With the never-ending need for screws or bolts, engineers of the time also used bolt-cutting machines.
In spite of the use of bolt-cutting machines, bolts were still made and used on a small scale until the occurrence of the Industrial Revolution. Once the Industrial Revolution happened, industrial bolts became a vital component in the engineering world.
During the 18th century, engineers designed the “first thread cutting machines”, clearing and paving the way for the mass production of screws. The reasons are different companies had their own standards for manufacturing industrial bolt threads, the market was flooded with an arrangement of different sized screw threads.
To overcome this problem, in 1841, Joseph Whitworth, an English engineer, came up with the idea of standardizing the size of the screw threads in industrial bolts. His recommendation was a standardized angle of the thread flanks and numbers of threads per inch. His efforts brought a change in the industrial bolts industry in Britain. Concurrently, across the Atlantic Ocean, American and Canadian engineers made similar efforts, making bolt threads standardized for specific diameters.\

Nut Fasteners

What is Nut Fasteners?

One of the types of a fastener is a nut with a threaded hole. Nuts which are almost always used while joining with a mating bolt to fasten various parts together.
In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins (split pins) or lockwire in connection with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads.
