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.
