DIN 251 standardized Hexagon flange screws (Hexagon flange screws) are fasteners with a hexagon drive slot and a flange face that are typically used where a large support surface is required or where loosening is to be prevented. These screws are characterized by a hexagonal head with a flange face, which provides a larger contact area and thus increases the stability of the connection.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Hex Drive: Hex drive slots allow for quick tightening and loosening with a hex wrench or power tool. FLANGE FACE DESIGN: The flange face provides a larger support area, which helps to distribute the tightening force and reduce stress on the connected parts. Anti-Loosening Performance: Anti-slip teeth on the flange face provide additional anti-loosening performance for use in vibrating environments. High-strength materials: usually made of high-strength steel, such as performance class 8.8, 10.9, 12.9, etc., with good mechanical properties and corrosion resistance.

Scope of Application

Mechanical Manufacturing: In the field of mechanical manufacturing, it is used to fix rotating or sliding parts such as gears, bearings and bushings. Automotive industry: in the engine, gearbox and other critical parts of automobiles to ensure the correct positioning and fixation of parts. Electrical equipment: In electrical equipment, used to keep electrical connectors and terminals in place and prevent loosening due to vibration. Aerospace: in the aerospace sector, to ensure the precise installation and fixing of critical components to withstand extreme operating conditions.
