Product Description

Product Description

All categories are available. Please consult customer service!

Size: The thread diameter is generally between M3 and M20, with a length range of 16mm to 400mm.
Tolerance: Comply with relevant tolerance standards, such as thread tolerance, bolt length tolerance, etc., to ensure the dimensional accuracy and interchangeability of the product.
Material properties: Commonly used stainless steel materials include A2 (304), A4 (316), etc. A2-70 indicates that the tensile strength of the stainless steel bolt is not less than 700MPa and the yield strength is not less than 400MPa; A4-80 indicates a tensile strength of not less than 800MPa and a yield strength of not less than 600MPa.
Corrosion resistance: Stainless steel material itself has good corrosion resistance. A2 stainless steel can maintain good performance in general atmospheric environments and moderately corrosive media, while A4 stainless steel has stronger corrosion resistance, especially in acid, alkali, salt solutions, etc., and is suitable for more harsh environments.
Connection function: mainly used to connect two or more parts together, providing fastening force by fitting with nuts to keep the parts in a relatively fixed position.
Anti loosening function: Some DIN6921 stainless steel bolts have serrations on the flange surface, which can prevent the bolt from loosening under vibration or impact by utilizing the friction between the serrations and the connected surface after tightening.
Flange face design: The bolt head is equipped with a flange face, which increases the contact area with the connected surface. It can evenly distribute the pressure of the bolt head on the connected surface, reduce surface pressure, avoid damage to the connected parts, and also improve the stability of the connection.
Easy to install: The hexagonal head design facilitates the use of tools such as wrenches for installation and disassembly, with simple and convenient operation, which can improve work efficiency.
Wide applicability: Due to its excellent performance and characteristics, DIN6921 stainless steel bolts are widely used in various industries such as automotive, machinery, construction, chemical, and food processing.
