List of Different Fasteners Types of Bolts

Bolts are the form of fastener. Fasteners are accustomed to obtain or fasten materials collectively. There are some cases of bolts and component nuts. Most, if not all, bolt cases take somebody threads. The threaded screw screws into eggs to make or fasten materials together. Bolt cases include heart bolts, bike bolts and machine bolts while types of eggs include top eggs, expansion nuts and u-nuts. The expert can tell you that about these types of nuts and bolts and the various types of bolt heads.


 

 

carriage bolt

Carriage Bolts

Also known as a “coach” bolt, has a domed or countersunk head. The square section under the head grips into the part being fastened preventing the bolt from turning when the nut is tightened.

hex bolt

Hex Head Bolts

Hex tap bolts, hex cap screws, trim head hex cap screws, and hex serrated flange bolts fall under this category. They share a hexagonal head and are driven with a wrench. Referred to as both bolts and screws.

machine screw

Machine Screws

A machine screw is a screw or bolt with a flat point. Available in a variety of drive types and heads, they fit a wide variety of applications. Often driven into tapped holes. Used with nuts and washers, also known as “stove bolts” or “stovers”.

shoulder bolts

Shoulder Bolts

Shoulder bolts (also known as shoulder screws or stripper bolts) are machine screws with a shoulder between the thread of the screw and the head of the part. Once installed, the non-threaded portion extends out of the surface of the application site, allowing the bolts to act as dowels or shafts for moving parts. They can be installed by hand or with a socket (Allen) driver.

socket cap screw

Socket Cap Screws

Socket cap screws are available in button socket, button flange socket head, flat socket, and socket cap. Driven with a socket wrench or a hex Allen key. The term socket head cap screw typically refers to a type of threaded fastener whose head diameter is nominally 1.5 times or more than that of the screw shank diameter.

socket set screw

Socket Set “Grub” Screws

Set screws are most often headless (aka blind), meaning that the screw is fully threaded and has no head. A blind set screw, known in UK as a grub screw, is almost always driven with an internal wrenching drive, such as a hex Allen key. Socket set screws are installed in threaded holes or inserts.

Square Head Bolts

Square Head Bolts

Square Head Bolts are similar to hex cap screws but with a 4-sided head. This head style allows for a wrench to grip more easily onto the head of the bolt. The head also provides a larger gripping area as compared to a standard 6-sided hexagonal head.

 

List of Different Fasteners Types of Screws

The screw can usually have a front on one point that contains a specially shaped structure that allows it to be worked, or forced, with the way. General instruments for taking screws include screwdrivers and wrenches. The top is usually larger than the structure of the screw, which prevents the screw from being pushed thicker than the size of the screw and to give the bearing device. There are exclusions; for example, Carriage bolts have a domed front that is not planned to be pushed; put screws frequently take the head smaller than the outer length of the screw; J-bolts take the J-shaped head which is not designed to be driven, But instead is normally buried into concrete allowing it to be utilized as the anchor bolt. This rounded part of the screw from the bottom of the head to this top is called the shank; it may be fully threaded or partly threaded. The point between each thought is called this. List of Different Fasteners,

Deck Screw

Deck Screws

Wood screws are partially threaded with large cutting threads and a smooth shank. They are designed to slide through the top piece of wood and tightly pull all boards together.


List of Different Fasteners Types of Nuts

Nut are available in a variety of shapes, sizes, fabrics, and thought shapes. While the choice of the seed is slightly restrained by the selection of bolt—particularly in terms of magnitude and threading—you even should determine that seed top structure and substance that is most suitable for your application.The types of nuts we stock include: Washers are disk-shaped components that provide enhanced control over locking and friction when used with other fasteners. These fasteners may also have teeth, indentations, and other specific functional mechanisms for function in more specific applications. As a summary, they provide a variety of purposes, including preventing adjustment of the fastener machine, protecting the device under the fastener, and distributing the force more evenly during installation and use.

Break Away nuts

Break Away or Shear Nuts

Shear nuts are cone nuts with a hexagonal gripping point. They are designed with an intentional flaw to snap the hexagonal head off once the maximum torque is reached. Leaving behind a protective cone nut that cannot be easily removed.

Tri-groove security nuts

List of Different Fasteners Types of Washers

Washers are normally metal or solid. High-quality bolted joints need hardened metal washers to keep the loss of pre-load due to brinelling after that force is used. Washers are also critical for keeping galvanic deterioration, especially by insulating steel screws from metal surfaces. They may also be employed in rotating applications, as the manner. The thrust washer is used when the moving factor bearing is not taken either from the cost-performance position or because of location constraints. Coatings may be used in effort to decrease wear and friction either by hardening their device, or offering a strong lubricant. List of Different Fasteners,

List of Different Fasteners Types of Rivets

The riveted connection is a permanent connection which uses rivets to secure two materials. The rivet is one system that has a hemispherical top on one side and a cylindrical arm on the other. Created from metal alloys, steel, or CRES and additional extra metals like titanium, metal, etc. These riveted joints have a broad variety of applications ranging from aircraft bodies to higher force boilers. There some cases of rivets, with the simplest procedure being the following: This rivet is enclosed into a pre-drilled mouth of the one length and the other point is ‘ upset ’ i.e. Deformed to a length that is 1.5 times higher than the first length. In riveted joints, more than one rivet is usually used to attach these materials, placed in a particular arrangement that is either parallel to each other or works at the zigzag manner. Riveted joints are powerful and can handle high stress (particularly in shear ), yet they may also go with the higher amount of tension force. List of Different Fasteners,

Machine screw anchors are installed into masonry materials in a pre-drilled hole. Once placed inside the hole, a machine screw is threaded into the anchor and tightened. As the machine screw is tightened, a coned portion is pulled into the sleeve causing it to deform. This deformation of the sleeve results in a tight wedge inside the hole that cannot be easily removed.

masonry anchor

Masonry Screws

Concrete masonry anchors, also known as Tapcons, cut threads into concrete, brick or block when installed. Extended corrosion protection is gained from the blue climaseal coating. No hole spotting or inserts required.

Plastic Hollow Wall Toggle Anchors

Plastic Toggle Anchors

Plastic toggle anchors are used in hollow wall or cinder block to create a fastening point for sheet metal screws. These anchors have legs that fold to enter a pre-drilled hole that expand when a screw is driven into them. Once the legs are fully expanded, the toggle anchor is securely in place.

Sammys Screws

Sammy Screws are used with threaded rod and save time by drilling into masonry materials. They have a female threaded portion to accept the threaded rod into it. Sammys are installed either vertically or horizontally and are commonly used due to their lower installation costs, flexibility and ease of use.

sleeve anchor

Sleeve Anchors

Concrete masonry sleeve anchors consist of a threaded stud with an outwardly flared cone-shaped end, with a nut and a washer on the end. Tightening of the nut pulls the stud end into the expander sleeve, wedging it outwards and locking the anchor into the base material. Made for hollow concrete applications (ex. cinderblocks).
