Professional Applications & Engineering Value

This M14 hex head screw delivers critical engineering advantages through its Class 8.8 steel construction and zinc-plated finish, specifically engineered to address common industrial challenges. The fine 1.5mm pitch and Class 6h thread fit prevent loosening under vibration while maintaining precise alignment in machinery assembly, structural frameworks, and heavy equipment. The fully threaded design ensures maximum clamping force distribution across the entire 45mm length, eliminating weak points in critical joints. With Rockwell C21 hardness and ISO 8676 compliance, this metric fastener provides reliable performance in automotive manufacturing, industrial machinery, and construction applications where consistent torque values and long-term durability are essential.

Specification Summary & Compliance

Manufactured to ISO 8676 standards (equivalent to DIN 961) with Class 6h thread tolerance ensuring precise dimensional accuracy. The metric coarse thread with right-hand direction and 1.5mm pitch provides optimal engagement characteristics. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance adherence. The Class 8.8 strength rating corresponds to mechanical properties including 110,000 psi tensile strength and Rockwell C21 hardness, validated through standardized testing protocols.
