Professional Applications & Engineering Value

This M14 hex head screw delivers exceptional engineering value through its Class 8.8 steel composition and fine thread pitch design. The combination of 110,000 psi tensile strength and Rockwell C21 hardness ensures reliable performance in structural applications where vibration resistance and load distribution are critical. The zinc plated finish provides essential corrosion protection for outdoor equipment, machinery assemblies, and construction projects exposed to environmental elements. The fully threaded design with Class 6h thread fit guarantees precise mating with corresponding nuts and threaded holes, minimizing the risk of cross-threading while maintaining consistent clamping force across the entire 35mm length. These metric screws are particularly valuable in manufacturing, automotive, and industrial maintenance applications where standardized external hex drive compatibility and predictable performance are essential for efficient assembly operations.
