Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M16 flat head screws solve critical fastening challenges in machinery assembly, structural frameworks, and heavy equipment manufacturing. The zinc-plated alloy steel construction combined with Class 10.9 strength rating provides exceptional resistance to dynamic loads and environmental degradation. The fully threaded metric design with coarse 2mm pitch ensures rapid installation and maintains secure connections even under severe vibration conditions. The standard 90° countersink angle and flat head profile enable flush mounting in precision applications where surface clearance is critical. These high tensile strength screws deliver reliable performance in construction, automotive, and industrial manufacturing where failure is not an option.
Specification Summary & Compliance
Manufactured to DIN 7991 standards with Class 6g thread fit precision and metric coarse threading (M16x2mm). The 50mm length features fully threaded construction with right-hand thread direction. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable industrial use. The Rockwell C32 hardness and 120,000 PSI tensile strength verify consistent performance across all production batches.
