Professional Applications & Engineering Value

This M16 hex head screw delivers critical engineering advantages for industrial applications where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel construction prevents rust and degradation in challenging environments, while the 100,000 psi tensile strength ensures reliable performance under heavy loads. The metric coarse thread (M16x2) with Class 6g tolerance provides excellent engagement in steel frameworks, machinery assembly, and structural connections. The partially threaded design concentrates thread engagement where needed most, reducing installation time and minimizing stress concentrations. These industrial hex bolts are particularly valuable in construction, manufacturing, and marine applications where corrosion resistant fasteners must maintain integrity over extended service life.

Specification Summary & Compliance

This metric hex head screw features precise M16x2 coarse threads with Class 6g thread fit according to ISO metric standards. The fastener complies with ISO 4014/DIN 931 specifications for dimensional accuracy and mechanical properties. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance. The partially threaded configuration with 38mm minimum thread length and 190mm overall length meets industrial requirements for structural bolting applications.
