Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M8 hex head screws provide critical solutions for vibration-prone environments where fastener integrity is paramount. The zinc-plated steel construction offers essential corrosion protection while maintaining the Class 8.8 strength rating required for structural applications. The expanding sleeve locking mechanism addresses common industrial challenges by creating permanent resistance against rotational loosening, making these fully threaded screws ideal for machinery, equipment frames, and structural assemblies subjected to continuous stress. The coarse thread design ensures rapid installation in various materials while the external hex drive accommodates standard tools for maintenance accessibility. With ISO 4017 DIN 933 compliance, these metric screws deliver standardized performance across global engineering specifications.

Specification Summary & Compliance

Manufactured to precise Class 6g thread fit tolerances with M8 x 1.25mm coarse thread spacing, these hex head screws meet rigorous ISO 4017 DIN 933 standards for dimensional accuracy and mechanical properties. The Rockwell C22 hardness rating ensures optimal durability while the 69,600 PSI shear strength provides critical failure resistance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and chemical safety standards for international industrial applications.
