Professional Applications & Engineering Value

These M10 hex head screws deliver exceptional engineering value in heavy-duty industrial applications where vibration resistance and long-term reliability are critical. The Class 8.8 steel construction combined with fine metric threading (M10 x 1.25 mm) creates superior clamping force distribution, effectively preventing joint loosening in machinery, structural assemblies, and equipment manufacturing. The zinc plated finish provides essential corrosion protection for outdoor installations or environments with moisture exposure. With full threading along the 25 mm length, these external hex drive fasteners ensure maximum thread engagement in both thick and thin materials, making them ideal for applications requiring consistent high tensile strength and dimensional stability across varied assembly conditions.

Specification Summary & Compliance

This metric hex head screw features precise M10 x 1.25 mm fine threads with Class 6h thread fit tolerance for accurate mating with corresponding nuts and threaded holes. Manufacturing complies with ISO 8676 specifications (equivalent to DIN 961) ensuring dimensional consistency and mechanical performance. The fastener meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) regulations regarding chemical safety. With Class 8.8 strength rating, Rockwell C21 hardness, and 110,000 psi tensile strength, these screws deliver reliable performance in accordance with international engineering standards for industrial fastening applications.
