Professional Applications & Engineering Value
This M16 hex head screw delivers critical engineering solutions where high tensile strength and durability are paramount. The Class 10.9 steel construction withstands extreme mechanical stresses in heavy machinery, structural steel connections, and industrial equipment assembly. Its fully threaded metric design ensures maximum thread contact in thick materials, preventing loosening under dynamic loads. The coarse 2mm pitch enables rapid installation in production environments while maintaining Class 6g thread fit precision. ISO 4017 compliance guarantees dimensional accuracy for replacement and OEM applications across global standards. Ideal for construction, automotive, and manufacturing sectors requiring reliable industrial fasteners that meet stringent regulatory and performance demands.
Specification Summary & Compliance
Manufactured to ISO 4017 specifications (equivalent to DIN 933) with Class 6g thread tolerance for precise fit. The metric coarse thread (M16 x 2mm) and 45mm length provide standardized dimensions. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Class 10.9 strength grade corresponds to minimum 150,000 PSI tensile strength and Rockwell C32 hardness, meeting international mechanical property requirements for high-strength fasteners.
