Professional Applications & Engineering Value
This M10 hex head screw delivers critical engineering advantages for industrial assembly where vibration resistance and long-term reliability are paramount. The Class 8.8 steel construction combined with fine metric threading (M10x1.25) creates secure, precision fits that resist loosening under dynamic loads. The zinc plated finish provides essential corrosion protection for machinery, equipment frames, and structural components exposed to environmental elements. With full threading along its 20mm length, this fully threaded fastener offers maximum engagement depth for critical joints in automotive, manufacturing, and construction applications where consistent clamping force is essential.
Specification Summary & Compliance
This metric fastener features precision Class 6h thread fit with right-hand fine thread spacing (1.25mm pitch) meeting ISO 8676 (DIN 961) manufacturing specifications. The product maintains dimensional accuracy with 6.4mm head height and 17mm head width for consistent tool engagement. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across regulated industries, while the external hex drive configuration provides standardized installation compatibility.
