  • Precise extended tip (4.3mm length) ensures accurate positioning and improved grip on mating components
  • Full regulatory compliance with RoHS 3 and REACH standards for safe use in global industrial markets
  • Optimized for heavy-duty applications with 80mm length providing deep engagement in machinery and structural assemblies
  • Standardized dimensions per DIN 479 specification guarantee interchangeability and consistent performance

Professional Applications & Engineering Value

This M16 metric set screw delivers critical engineering advantages through its alloy steel composition and specialized design. The square head configuration with external drive enables high-torque installation without cam-out, solving common fastening challenges in heavy machinery assembly. The coarse thread pitch (2mm) combined with Class 6g thread fit provides exceptional resistance to vibrational loosening in dynamic industrial environments. The extended tip design creates positive locating and enhanced clamping force distribution, making it ideal for precision equipment alignment, shaft securing applications, and permanent fastening in construction machinery. These features collectively address critical concerns of joint integrity, installation efficiency, and long-term reliability in demanding industrial fastening scenarios.

Specification Summary & Compliance

Manufactured to DIN 479 standards with Class 6g thread tolerance for precision fit. Thread specifications include M16x2mm coarse pitch with right-hand orientation. Tip dimensions maintain tight tolerances (length: 4.3mm [-0.3mm to 0], diameter: 12mm [-0.27mm to 0]). Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures global market acceptance.
