Professional Applications & Engineering Value
This M10 hex flange screw delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for industrial equipment, machinery assemblies, and outdoor applications. The serrated locking flange creates permanent friction against mating surfaces, effectively preventing loosening in high-vibration environments like automotive components, power transmission systems, and heavy machinery. With Class 8.8 strength rating and 110,000 psi tensile strength, this fully threaded metric screw maintains joint integrity under significant mechanical stress. The coarse 1.5mm pitch threading ensures rapid installation while the external hex drive accommodates standard tools for efficient assembly in confined spaces.
Specification Summary & Compliance
This fastener features M10 x 1.5mm coarse thread with Class 6g thread fit tolerance per metric standards. Manufacturing complies with DIN 6921 specifications for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety. With Rockwell C22 hardness and verified mechanical properties, this hex flange screw delivers consistent performance across industrial applications.
