Professional Applications & Engineering Value

This M16x2mm Class 10.9 metric screw with black-oxide alloy steel construction addresses critical industrial challenges, including corrosion in humid or chemical-exposed settings. The fully threaded hex screw design ensures maximum grip length for structural assemblies, machinery, and automotive components, while the ISO 7380 compliant rounded head minimizes protrusion risks in tight spaces. With a 10mm hex drive and coarse thread, it speeds up installation in high-volume production lines, reducing labor time without compromising the 140,000 psi tensile strength needed for heavy-duty fastening.

Specification Summary & Compliance

Manufactured to ISO 7380 standards with Class 6g thread fit and Metric M16x2mm coarse threading, this screw ensures dimensional accuracy for reliable mating. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally conscious procurement. The Class 10.9 strength grade and Rockwell C32 hardness further validate its adherence to rigorous industrial specifications.
