Professional Applications & Engineering Value

This M6 set screw delivers critical engineering solutions for permanent fastening applications where vibration resistance and positional security are paramount. The black-oxide alloy steel construction provides superior corrosion resistance while maintaining the Rockwell C45 hardness necessary for high-stress industrial environments. The nylon patch thread locker eliminates the need for additional locking compounds, creating a permanent bond that withstands temperature fluctuations from -50° to 250°F. The cup point tip design bites into mating surfaces, preventing rotational movement in pulleys, gears, and collars. With Class 5g6g thread fit precision and hex drive installation, this metric set screw ensures reliable performance in machinery, automotive, and manufacturing applications where disassembly is not anticipated.

Specification Summary & Compliance
