Automotive manufacturing: In the process of automotive manufacturing, square head bolts are used to secure automotive components such as engines, transmissions, etc.
Product description: Hexagonal tail punch bolts are also called opening holes and safety hole screws. Common standards include GB/T31.1. They are mainly used to prevent the workpiece from loosening after the equipment is fastened and connected. They are mainly used to prevent the bolts from vibrating and loosening during use, so they are also called safety hole screws.
1.the small yellow croaker expansion screw is relatively strong, the small yellow croaker expansion screw tension is strong, can better play a fixed and stable role. When installing, be sure to tighten, screw in place, and then beat with a hammer, not only beautiful knot reliable with firm and stable fixed stable effect is particularly good. 2. especially suitable for hanging, arch structure, outdoor walls, stairs, radiators and other different occasions of columns, Angle steel, beams and other parts fixed and supported. The crosshead expansion screw is a kind of expansion screw, which is characterized by a variety of dimensions, convenient installation and firm fixing. Small yellow croaker expansion screw, the appearance is like a small fish, its main feature is shaped like a “hollow bolt” and has good expansion.
Stud is used to connect the fixed link function of the machine, both ends have threads, the middle is a screw, there are thick and thin. The thick one is called the thick rod or type A, and the thin one is called the thin rod or type B. Mainly used for connecting parts too thick do not use bolts or due to frequent disassembly should not use screw connection occasions, the stud is usually one end screwed into the screw hole, one end is connected with a nut. Each end of an equal length stud is configured with nuts. Generally used in mining machinery, bridge construction, automobiles, motorcycles, boiler steel structure, hanging tower, long-span steel structure and large buildings, flange connectors, machinery and equipment, pipelines, pump plants, motor plants, construction projects, sewage pipes, machine tools, engines and so on.

DIN929 welded hex nuts are mainly used in scenarios that require high-strength connections and special shaped connections. This type of nut is connected to the connector by welding and is suitable for situations where conventional bolt connections cannot be made, such as when the connector is too thin or irregularly shaped. The welding process is equivalent to turning two separate parts into a whole, melting the metal at high temperature, mixing it together, and then cooling it. An alloy is added in the middle, relying on molecular force, and its strength is generally greater than that of the parent material.
