  • Superior wear resistance from alloy steel construction hardened to Rockwell C22, ensuring long-term durability under heavy loads
  • Precision Class 6g thread fit guarantees consistent engagement and reduces the risk of cross-threading during assembly
  • Extended 4.3mm tip with controlled diameter provides deeper penetration and enhanced grip for secure component positioning
  • Robust square head with external drive offers high torque capability and resists stripping, even with repeated use
  • Full compliance with DIN 479 specifications ensures dimensional accuracy and interchangeability in metric fastener systems
  • Environmentally responsible manufacturing meeting RoHS 3 and REACH regulations for safe use in global industrial supply chains

Professional Applications & Engineering Value

This M16x2mm metric set screw is engineered to solve critical challenges in industrial machinery and heavy-duty equipment assembly. The alloy steel core, combined with a Rockwell C22 hardness, provides exceptional resistance to vibrational loosening and shear forces, making it ideal for permanent positioning of gears, pulleys, and collars on shafts. The coarse thread design enables faster installation in tough materials, while the extended tip ensures maximum surface contact for a secure, non-slip hold. Manufactured to DIN 479 standards with a Class 6g thread fit, it delivers reliable performance in high-stress environments where precision and repeatability are paramount.

Specification Summary & Compliance

This square head set screw features an M16x2mm metric coarse thread with a Class 6g tolerance for precise fit. The extended tip has a diameter of 12 mm (-0.27mm to 0 tolerance) and length of 4.3 mm (-0.3mm to 0 tolerance). It is manufactured in compliance with DIN 479 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
