Professional Applications & Engineering Value
These Class 8.8 hex head screws with black corrosion-resistant coating deliver exceptional performance in demanding industrial settings. The M8 coarse thread configuration (1.25mm pitch) provides superior resistance to vibration-induced loosening while enabling rapid installation in production environments. The integrated flange design distributes clamping force effectively, preventing surface damage and maintaining joint integrity. Manufactured to DIN 6921 specifications with Class 6g thread fit, these fully threaded metric screws ensure precise engagement in machinery, structural assemblies, and equipment manufacturing where 110,000 psi tensile strength and consistent Rockwell C22 hardness are critical for long-term reliability.
Specification Summary & Compliance
This M8 x 1.25 x 20mm hex head screw features Class 6g thread tolerance per metric standards and complies with DIN 6921 manufacturing specifications. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental responsibility and workplace safety. With 18mm flange diameter and 13mm hex head dimensions, the screw maintains precise engineering tolerances for consistent performance in industrial fastener applications.
