Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M16 hex head screws deliver exceptional mechanical performance where reliability is critical. The Class 10.9 steel construction provides a tensile strength of 150,000 psi, making them ideal for heavy machinery, structural assemblies, and equipment requiring high clamp load retention. The partially threaded design with 38mm minimum thread length offers optimal stress distribution, reducing the risk of thread stripping while the coarse metric thread ensures rapid installation in various materials. With external hex drive compatibility, these fasteners enable efficient assembly using standard tools, significantly reducing installation time in manufacturing, construction, and automotive applications where ISO 4014/DIN 931 compliance is mandatory for quality assurance.
Specification Summary & Compliance
This M16 x 2mm hex head screw features precise Class 6g thread fit tolerance and 80mm overall length with partial threading. Manufactured to ISO 4014/DIN 931 standards for dimensional accuracy and mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors. The fastener meets all specified requirements for Class 10.9 strength grade with verified Rockwell C32 hardness and 150,000 psi tensile strength performance.
