What Are the Different Types of Bolts?

Different Types of Bolts

Bolts are also known as a mechanical fastener has external threads and always combined with a nut. These bolts can insert through holes and connect two parts using tightening torque. For proper functioning, bolds requires a nut and drilled hole into which one can insert the Duplex Steel Bolts/Screw.

Following are the types of bolts:

Anchor Bolts

These bolts attach to a structural component to a concrete slab or foundation. Anchor bolts are useful in applications where the cast concrete structure. The bolt plate is placed on the upper surface of the poured foundation.

Arbor bolts

These bolts have the fixed washer and show the reversed threading. Arbor bolts are applicable in tools such as the miller saw. These bolts allow secure the position of tools, and the blade doesn’t fall out.

Blind Bolts

Blind bolts are useful in applications requiring fastener. Besides, these bolts are eligible to use where there is no access allowed to both sides of the bolt to tighten the bolt.

Carriage bolts

Carriage bolts are also known as round head square neck bolts. Carriage bolts have a seamless round head and a square-shaped section. Here, the square prevents the turning of a bolt. Besides, these bolts have a threaded portion for a nut. These bolts are useful in fastening metal to wood.

Hanger bolts

These bolts are free of heads but consist of a machine threaded portion and a wooden threaded screw tip. These are the studs and useful to suspend objects from wood or attached objects to timber. Each part of a hanger bolt has threads, lag threads on one end and machine screw threads on the other end to allow the insertion of nut into a hole.

Hex bolts

These are the commonly used bolts and known as standard bolts. These bolts are available in three standard lengths, or grades and diameter as well. The size of these bolts varies from ¼ inches to 4 inches. Hex bolt offers more strength and easy to assemble and torque.

Double-end bolts

These are popularly known as stud bolts and they have two threaded ends. Additionally, in double-end bolts head is absent. Here, one end has threads to support a hole tapped with a mated thread. In contrast, the other end supports a nut. The double end bolt looks similar to that of a threaded rod.
