Product Description

The M6x20 hex flange screws, compliant with DIN 6921 flange bolts standard, are metric flange screws designed for robust fastening in mechanical assemblies. These screws feature a hexagonal head with an integrated flange for distributed load bearing, eliminating the need for separate washers. With a thread diameter of 6 mm and a 20 mm shank length, they are constructed from grade 8.8 steel, offering tensile strength up to 800 MPa. Typical applications include automotive components, machinery frames, and electrical enclosures. Operating temperature ranges from -50°C to +120°C, suitable for industrial environments. Advantages include vibration resistance and simplified installation, though flange diameter limitations may restrict use in space-constrained applications. Surface treatments like zinc plating enhance corrosion resistance for outdoor use.
