Professional Applications & Engineering Value

These M16 hex head screws deliver critical engineering solutions for heavy-duty industrial applications where fastener failure is not an option. The Class 10.9 steel construction provides exceptional strength-to-weight ratio, while the 2 mm coarse pitch metric thread ensures rapid assembly without compromising holding power. The partially threaded design offers dual functionality: the threaded section provides secure fastening, while the unthreaded shank maintains alignment in structural connections. With external hex drive compatibility, these DIN 931 compliant fasteners enable efficient installation in confined spaces using standard wrenching tools, making them ideal for machinery, construction, and equipment manufacturing where reliability and ease of maintenance are paramount.

Specification Summary & Compliance

This high-strength hex head screw features precise Class 6g thread fit according to ISO metric standards, ensuring proper engagement with mating components. Manufacturing follows DIN 931 specifications for dimensional accuracy and mechanical properties. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. With M16 x 2 mm coarse thread configuration and 155 mm total length (38 mm minimum thread length), this screw meets international quality standards for industrial fastening applications requiring certified performance and environmental responsibility.
