Professional Applications & Engineering Value

This M8 hex head screw delivers exceptional engineering value through its Class 10.9 steel construction and metric coarse threading. The combination of 150,000 psi tensile strength and Rockwell C32 hardness addresses critical industrial challenges where fastener failure is not an option. The partially threaded design with 22mm minimum thread length provides optimal clamping force distribution while preventing material distortion in assembly applications. Engineered to DIN 931 standards, this external hex drive fastener ensures consistent performance in machinery, structural frameworks, and heavy equipment where vibration resistance and long-term reliability are paramount. The black steel composition offers additional protection against environmental factors, making it suitable for both indoor and outdoor industrial settings.

Specification Summary & Compliance

This metric hex head screw maintains precise dimensional accuracy with Class 6g thread fit and standardized M8 x 1.25mm coarse thread parameters according to DIN 931 specifications. The manufacturing process adheres to strict quality controls ensuring consistent 180mm length with 5.3mm head height tolerances. Regulatory compliance includes full conformity with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) chemical safety standards, providing assurance for environmentally conscious procurement decisions in industrial supply chains.
