Professional Applications & Engineering Value
This M12 hex head screw delivers critical engineering solutions where vibration resistance and long-term reliability are paramount. The extra fine thread spacing (1.25mm pitch) provides superior holding power in materials prone to stress relaxation, while the Class 8.8 strength rating ensures consistent performance under dynamic loads. The zinc plated finish creates a protective barrier against corrosion in manufacturing facilities, outdoor equipment, and automotive assemblies. With fully threaded design and external hex drive, installation efficiency is maximized while maintaining precise Class 6h thread fit for secure fastening in critical joints and structural connections.
Specification Summary & Compliance
Manufactured to ISO 8676 DIN 961 standards with Class 6h thread tolerance for precision fit. The metric coarse thread (M12 x 1.25mm) features right-hand direction and fully threaded 25mm length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Mechanical properties include Rockwell C21 hardness and 110,000 psi tensile strength per Class 8.8 specifications.
