Professional Applications & Engineering Value
This M16 metric hex set screw delivers critical engineering solutions for heavy-duty industrial applications where vibration resistance and positional accuracy are paramount. The Class 8.8 steel construction and Rockwell C20 hardness provide superior resistance to dynamic loads and environmental degradation, preventing loosening in machinery, automotive assemblies, and construction equipment. The coarse metric thread (M16x2mm) with Class 6g tolerance ensures rapid installation and reliable grip in both soft and hard materials, while the extended tip concentrates pressure for secure shaft positioning. Compliant with DIN 561B, this fastener meets rigorous German engineering standards, making it ideal for OEM and MRO applications requiring high-strength set screws with documented traceability.
Specification Summary & Compliance
This set screw maintains Class 6g thread fit per ISO metric standards with precise dimensional control (tip diameter: 12mm [-0.27mm/0], tip length: 8mm [0/0.36mm]). Manufacturing and material properties adhere to DIN 561B specifications, ensuring consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally regulated markets and industrial applications demanding material transparency.
