- Rockwell C21 hardness maintains thread integrity and prevents stripping during repeated use
Professional Applications & Engineering Value
Engineered for industrial machinery, structural assemblies, and heavy equipment, these M16 hex head screws deliver exceptional reliability where vibration resistance and load-bearing capacity are critical. The Class 8.8 steel construction combined with zinc plating addresses common failure points by preventing corrosion-induced weakening and maintaining clamp force over time. The coarse metric thread (2mm pitch) ensures rapid installation in steel frameworks and aluminum components while the external hex drive accommodates high torque requirements without slippage. These fully threaded fasteners provide uniform stress distribution, making them ideal for construction, automotive, and manufacturing applications where joint integrity cannot be compromised.
Specification Summary & Compliance
Manufactured to ISO 4017, DIN 933, and SAE J1199 standards with Class 6h thread fit for precise dimensional accuracy. The 45mm length and M16 x 2mm coarse thread maintain consistent engagement across mating surfaces. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial supply chains.
