Professional Applications & Engineering Value

Engineered for demanding applications, this M8 flanged hex button head screw delivers exceptional value in machinery assembly, automotive components, and electronic enclosures. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to oxidation and chemical exposure, significantly extending service life in corrosive environments. The integrated flange distributes clamping force over a wider area (17.8mm diameter), preventing surface damage and loosening under vibration. The coarse metric thread (M8 x 1.25mm) and Class 6g fit ensure rapid, secure fastening in a variety of substrates, reducing installation time and improving production line efficiency. This screw is a robust solution for engineers seeking a reliable, fully threaded fastener that combines strength with ease of use.

Specification Summary & Compliance

This screw conforms to the dimensional and mechanical specifications of ISO 7380. The metric thread has a size of M8, a coarse pitch of 1.25mm, and a Class 6g tolerance for a consistently reliable fit. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for use in global markets.
