Nuts are fastening parts that are used in conjunction with bolts. They are usually in the shape of a hexahedron or other shapes, with an internal threaded hole in the center that meshes with the external threads of the bolt to achieve fastening. There is a wide variety of nut specifications, which are distinguished according to parameters such as the diameter and pitch of the thread. Types include common nuts and lock nuts. The manufacturing materials include carbon steel, stainless steel, alloy steel, etc., in order to adapt to different application scenarios. They are widely used in fields such as industrial manufacturing, construction engineering, and daily life, playing a crucial role in ensuring the stability and reliability of connections.

DIN6923/Hexagon Flange Bolt

The information of DIN6923 is as follows:

diameter:       3  4  5  6  8 10 12 14 16 20
material:   304      316  D2-80      carbon steel       copper
thread form:   Coarse thread         and so on
surface finishing:    natural          coating        black        galvanizing       Dacromet coating   and so on

DIN934 /hexagon 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.
