DIN6921 Stainless Steel Serrated Hex Flange Bolt

Product Description

DIN6012 Stainless Steel Serrated Hex Flange Bolt Product Description Hexagonal flange bolts are special bolts with a flange surface, combining the fastening function of traditional bolts with the anti - loosening performance and increased support surface of the flange. During the connection process, by rotating the nut, the threaded part of the bolt cooperates with the threaded hole of the connected parts to achieve a tight connection. The flange surface provides a larger contact area, effectively dispersing pressure and enhancing the stability of the connection.
Product Features 1. Good Anti - loosening Performance: The toothed design on the flange surface can increase the friction with the surface of the connected parts, effectively preventing the bolt from loosening in a vibrating or impact environment and ensuring the long - term reliability of the connection.
2. Increased Support Surface: Compared with ordinary bolts, the flange surface provides a larger support area, reducing the pressure per unit area and avoiding damage to the surface of the connected parts due to pressure concentration. It is suitable for connected parts made of various materials.
3. Easy Installation: The standard hexagonal head design is convenient for operation with common tools such as wrenches. The installation process is simple and efficient, which can improve work efficiency and reduce installation costs.
4. Strong Versatility: It is widely used in different industries and fields. Whether it is the connection of light - duty structures or heavy - duty equipment, it can exert its good fastening performance and meet diverse connection needs.
Product Material 1) Carbon Steel: It has a relatively low cost and good comprehensive mechanical properties. After appropriate heat treatment, it can meet the strength requirements of general industrial and construction fields and is one of the most commonly used materials.
2) Stainless Steel: It has excellent corrosion resistance and can still maintain good performance in harsh environments.
3) Alloy Steel: Added with various alloying elements such as chromium (Cr), molybdenum (Mo), and vanadium (V), which significantly improves the strength, hardness, and toughness of the bolt. It is suitable for special applications with extremely high requirements for strength and performance.
