Professional Applications & Engineering Value
These M12 hex head screws deliver exceptional engineering value in demanding industrial applications where vibration resistance and corrosion protection are critical. The Class 8.8 steel construction combined with zinc plating addresses common failure points in machinery assembly, automotive components, and structural frameworks. The metric fine threading (1.5mm pitch) ensures superior holding power in materials prone to stress relaxation, while the partial threading design allows for precise unthreaded shank sections where shear strength is paramount. These industrial hex screws solve alignment challenges in heavy equipment manufacturing and prevent galvanic corrosion in mixed-material assemblies, making them ideal for OEM applications requiring ISO 8765 compliance and long-term reliability.
Specification Summary & Compliance
This M12 hex head screw features precise Class 6h thread fit tolerance with 55mm total length and 30mm minimum thread length. Manufactured to ISO 8765 specifications (equivalent to DIN 960) with right-hand metric fine threading. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The external hex drive configuration and 19mm head width ensure compatibility with standard industrial tools, while the Rockwell C21 hardness and 110,000 psi tensile strength guarantee performance consistency across production batches.
