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.
