Stainless steel hexagon socket bolt is a commonly used fastener, also known as stainless steel cylindrical head hexagon socket screw or stainless steel cup head screw. The material of this type of bolt mainly includes stainless steel SUS201, stainless steel SUS304, stainless steel SUS316, etc. It has the characteristics of oxidation resistance, high temperature resistance, and corrosion resistance, and is widely used in electronic products, electrical, furniture and other fields. The standards for stainless steel hexagonal bolts include two types: those with and without rolling patterns on the head, and their strength grades generally include 4.8, 8.8, 10.9, 12.9, etc. In addition, understanding the national standard for hexagonal bolts is very helpful when selecting stainless steel hexagonal bolts.
Texture of material
Usually made of SUS304 stainless steel wire. There are two types of stainless steel hexagon socket screws available on the market: head rolled and non rolled. Stainless steel hexagon socket screws generally cannot be distinguished from the quality of the material on the surface, but it can be judged from the production process of the screw (industry experience, for reference only): Generally, screws with straight grain rolling process on the head of stainless steel hexagon socket screws can be judged as authentic SUS304 produced screws. Stainless steel hexagon socket screws without rolled patterns on the head can be considered as products with slightly inferior material or low nickel content. But the specific analysis can still be based on the report issued by the quality inspection unit.
Stainless steel hexagon socket screws are a type of hole type screw commonly used in machine tools, chemical equipment, water pumps, ships, power equipment, and other places. Full tooth stainless steel hexagon socket screws are more commonly used, while half tooth stainless steel hexagon socket screws are more commonly used in export equipment in China. The material is divided into two types: SUS304 stainless steel hexagonal socket screws, with a strength level described as A2-70. SUS316 stainless steel hexagon socket screw, strength grade description - A4-70
Reference standards
DIN912 GB/T70.1 ISO4762 ANSIB18.3 JISB1176 It is worth noting that the size measurement of stainless steel pan head hexagon socket screws and stainless steel cylindrical head hexagon socket screws is described based on the effective length below the head. The stainless steel flat head hexagonal screw (also known as countersunk hexagonal screw) is a measuring screw SUS304 stainless steel screw. Simply put, it refers to the stainless steel wire used in the product with a nickel content standard of eight or more.
Raw material
The main materials used are austenitic 201, 304, 316, and 316L. Usually, only hex screws made of materials such as 201, 304, 316 are available in stock on the market, while others need to be processed and customized according to customer needs. The material selection of stainless steel hexagonal screws, etc., can be customized according to customer's drawings and samples.
