Professional Applications & Engineering Value
Engineered for demanding industrial applications, these Class 10.9 hex head screws deliver critical performance where failure is not an option. The high-strength steel construction combined with M8 coarse threading provides exceptional clamping force for machinery assembly, structural steel connections, and heavy equipment manufacturing. The fully threaded design ensures uniform stress distribution along the entire fastener length, preventing localized failure points in vibration-prone environments. With 150,000 PSI tensile strength and Rockwell C32 hardness, these black steel screws maintain integrity under extreme mechanical loads while the external hex drive facilitates efficient installation in confined spaces common in industrial settings.
Specification Summary & Compliance
This metric hex head screw features M8 x 1.25mm coarse threads with Class 6g tolerance for precise fitment. Manufactured to ISO 4017 and DIN 933 standards, the fastener delivers consistent dimensional accuracy. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material restrictions adherence. The 60mm length and fully threaded configuration provide versatile application coverage while maintaining Class 10.9 strength rating throughout the fastener body.
