Professional Applications & Engineering Value
This M6 hex headless set screw delivers exceptional engineering value in applications requiring precise component positioning and secure shaft retention. The 18-8 stainless steel material provides excellent corrosion resistance, making it ideal for machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The brass soft tip (1.6 mm length, 3.2 mm diameter) prevents galling and protects expensive shafts or precision surfaces from marring during installation. With its Class 6g thread fit and coarse metric thread design, this fastener ensures quick assembly and maintains clamping force in high-vibration environments. The headless configuration allows for flush mounting in space-constrained applications while the 3 mm hex drive provides sufficient torque capability for secure fastening.
Specification Summary & Compliance
This metric set screw features M6 x 1 mm coarse threads with Class 6g tolerance for precision fit. The 8 mm length and headless design provide compact fastening solutions. Manufacturing complies with ASME B18.3.6M specifications for dimensional accuracy and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring restricted substance compliance for global industrial applications.
