  • Enhanced vibration resistance through green nylon 6/6 plastic tip that maintains grip under dynamic loads from -50° to 250° F
  • High-strength performance with Rockwell C28 hardness alloy steel construction for reliable holding power
  • Precise thread engagement with Class 5g6g coarse metric threads ensuring consistent fastening in high-vibration applications
  • Space-saving headless design with 4mm hex drive for flush installation where clearance is limited
  • Industry-standard compliance meeting ASME B18.3.6M specifications for guaranteed interchangeability and quality
  • Environmental responsibility with full RoHS 3 and REACH compliance for sustainable manufacturing practices

Professional Applications & Engineering Value

This M8 set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and precise positioning are critical. The black-oxide alloy steel construction provides superior corrosion protection while maintaining Rockwell C28 hardness for maximum clamping force. The nylon 6/6 plastic tip creates a secure, mar-free contact surface that withstands temperature fluctuations from -50° to 250° F, preventing loosening in machinery, automotive assemblies, and precision equipment. The coarse metric thread with Class 5g6g fit ensures rapid installation and reliable performance in high-vibration environments, while the headless hex drive design allows for flush mounting in confined spaces. Engineered to ASME B18.3.6M standards, this set screw provides consistent quality and reliability for OEM and maintenance applications.

Specification Summary & Compliance

This metric set screw features M8 x 1.25mm coarse threads with Class 5g6g thread fit tolerance for precise engagement. The 16mm length with 2.4mm nylon tip provides optimal fastening depth. Manufactured to ASME B18.3.6M specifications and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The black-oxide surface treatment on alloy steel with Rockwell C28 hardness ensures durability and corrosion resistance in industrial applications.
