Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M12 hex head screws solve critical fastening challenges in machinery, structural assemblies, and heavy equipment. The zinc-plated steel construction provides essential corrosion protection while maintaining the Class 8.8 strength grade required for high-stress connections. The expanding sleeve locking mechanism addresses vibration-induced loosening - a common failure point in dynamic environments. With fully threaded metric coarse threading and external hex drive, these fasteners deliver rapid installation and superior clamping force for materials ranging from 1" to 1 13/16" thickness. The combination of 69,600 psi shear strength and precise Class 6g thread fit ensures reliable performance in critical joints where safety and durability are paramount.

Specification Summary & Compliance

Manufactured to ISO 4017 DIN 933 specifications with Class 6g thread tolerance for precise metric fitment. The M12 x 1.75mm coarse thread configuration ensures optimal engagement in various materials. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, alongside Class 8.8 mechanical properties meeting international strength standards for industrial fasteners.
