Professional Applications & Engineering Value

These M6 flanged hex button head screws are engineered to address common industrial challenges, such as vibration loosening and corrosion in demanding settings. Made from 18-8 stainless steel with a passivated finish, they resist rust and chemical exposure, extending service life in machinery, automotive, and electronics assemblies. The fully threaded coarse pitch and Class 6g fit enable fast, accurate installation with high clamp force, while the integrated flange distributes pressure evenly, preventing surface damage. Ideal for industrial applications requiring robust, ISO 7380 compliant fasteners, they simplify maintenance and enhance structural integrity without compromising on regulatory standards like RoHS and REACH.

Specification Summary & Compliance

This screw features an M6 x 1 mm metric coarse thread with Class 6g tolerance for precise fit, and is manufactured to ISO 7380 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met. Dimensions include an 8 mm length, 13.6 mm flange diameter, and 4 mm hex drive, supporting consistent performance in technical assemblies.
