Hexagonal nut

DIN934 can be classified according to the following materials:

1. Carbon steel: Such as C10 or C15 carbon steel, etc., are often used in general mechanical connection and fastening applications. There are also heat-treated carbon steel materials like grade 8.8 carbon steel, which can meet higher strength requirements.
2. Stainless steel: Usually A2 – 70 (equivalent to 304 stainless steel), it has good corrosion resistance and oxidation resistance, and is suitable for environments with high requirements for corrosion resistance, such as the chemical industry, food industry, medical device industry, etc.
3. Aluminum alloy: Such as ALMg4.5Mn or ALMg5, etc., has the characteristics of light weight and corrosion resistance, and is often used in fields with requirements for weight, such as aerospace and automotive manufacturing.
