Bolts Commonly Used In The Automotive Industry

A bolt is a commonly used fastener, usually used with a bolt or screw, to connect and fix two or more objects. Widely used in construction, machinery, automobile, aerospace, and other industries. Among them, the two most common bolts in the automotive industry, hex bolts, and flange bolts have the following main functions

(1)Hex bolts: Hex bolts are a type of fastener with six sides and are one of the most commonly used bolts in various applications. They are typically made of steel and brass and come in various sizes, thread pitches, and finishes. One of the advantages of hex bolts is their ease of use with a wrench or pliers, making them a convenient option for various assembly and maintenance tasks.

(2)Flange bolts: Flange bolts can provide a larger bearing surface for distributing the load and helps to prevent damage to the surface being fastened. Flange bolts are commonly used in applications where a high-strength connection is required, such as in the automotive, aerospace, and construction industries. They are often used to fasten components that are subject to vibration, such as engine mounts and suspension components. Flange bolts are available in a variety of materials, including carbon steel, alloy steel, and stainless steel, and are typically coated with a protective finish, such as zinc plating, to prevent corrosion.

As a well-known custom manufacturer and supplier of automotive hollow rivets in China, Foster Bolt has a variety of products, which are widely used in automotive chassis, automotive engines, automotive clutch assemblies, automotive brake series, hardware tools, etc.

Where Are Bolts Of Different Head Shapes Used?

Bolts are fasteners that are used in combination with bolts or threaded rods to join two or more objects together. Bolts come in various head shapes, and each head shape has its specific applications. Here are some examples of bolts with different head shapes and their common uses:

(1)Hex bolts: Hex bolts are the most common type of bolts and have a hexagonal shape. They are used in a wide range of applications, including construction, automotive, machinery, and general fastening purposes. Hex bolts are typically tightened with a wrench or a socket, and their six-sided shape provides a good grip for tightening and loosening.

(2)Square bolts: Square bolts have a square shape and are used in applications where a wrench or pliers can be used to tighten or loosen them. They are commonly used in woodworking, cabinetry, and other applications where a square hole is used in conjunction with the square bolt to prevent rotation.

(3)Flange bolts: Flange bolts have a wide, flat circular flange at one end, which provides a larger bearing surface and helps distribute the load over a wider area. Flange bolts are often used in applications where the bolt needs to resist loosening due to vibrations, such as in automotive, aerospace, and machinery applications.

(4)T-bolts: T-bolts, also known as tee bolts or blind bolts, have a T-shaped body and are used to create a threaded hole in wood or other soft materials. They are commonly used in woodworking, furniture, and cabinetry applications, where they can be inserted into a pre-drilled hole and then tightened with a bolt from the opposite side to create a strong threaded connection.

(5)Oval head bolts, also known as oval head bolts, are a special type of bolt with an oval head shape. Oval head bolts usually have two parallel flats forming an oval head, one of which is usually grooved or recessed for installation and removal using special tools or wrenches.
