M8 M10 M12 Grade 8.8 Carbon steel galvanized automotive welding bolts




Automotive welding bolts are special type of bolts used in automotive manufacturing and repair processes. They are designed to provide strong and reliable weld joints between metal parts, particularly for automotive body panels and chassis components.

There are different types of automotive welding bolts available in the market, but generally they can be categorized into two main types:

1. Spot welding bolts - These bolts are used for spot welding application, where multiple layers of metal sheets need to be joined together. They consist of a threaded bolt with a flat, flanged head that serves as the welding contact point. The bolt is inserted through the top sheet and screwed into a threaded nut on the bottom sheet, creating a fixture that can be easily welded.

2. Nut and stud welding bolts - These bolts consist of a threaded stud and a nut. The stud is inserted through a pre-drilled hole in the metal part and the nut is threaded onto the other end. The nut is then welded to the metal part, creating a strong and permanent welded joint.

Automotive welding bolts are made from high-strength materials such as stainless steel or hardened steel to withstand the stresses of welding and the extreme conditions of automotive use. They are also available in different sizes and shapes to fit various welding applications.

In addition to their strength and durability, automotive welding bolts offer several benefits to automotive manufacturers and repair shops. They allow for fast and efficient welding of metal parts, reduce the need for skilled welders, and minimize the risk of weld distortion or damage to the surrounding metal.

Overall, automotive welding bolts are an essential component in the automotive manufacturing and repair industry, providing a reliable and efficient solution for welding metal parts together.
