Professional Applications & Engineering Value
This M10 hex head screw delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The Class 8.8 steel construction provides reliable performance in heavy machinery, structural steel connections, and industrial equipment assembly. The zinc plated finish combats corrosion in harsh environments while the coarse thread with 1.5 mm pitch ensures superior grip in both metal and composite materials. With partial threading optimizing the 90 mm length, this fastener prevents joint loosening under dynamic loads, making it ideal for automotive frames, construction projects, and manufacturing equipment where safety and longevity are non-negotiable.
Specification Summary & Compliance
Manufactured to exacting ISO 4014 and DIN 931 standards with Class 6h thread fit tolerance for precision engagement. The metric coarse thread (M10 x 1.5 mm) ensures compatibility with standard components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, alongside meeting ISO 898 mechanical property requirements for Class 8.8 strength grade fasteners.
