  • Exceptional durability and corrosion resistance through black-oxide coated alloy steel construction with Rockwell C45 hardness
  • Precise thread engagement with Class 3A fit UNC coarse threads ensuring reliable fastening in demanding applications
  • Space-saving headless design with hex drive for flush mounting where clearance is limited
  • Optimized torque transmission through 3/32" hex drive that prevents stripping during installation
  • Enhanced grip and positioning with cup tip design that digs into mating surfaces for superior holding power
  • Industry compliance assurance meeting ASME B18.3 standards and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

This 10-24 UNC set screw delivers critical engineering solutions for industrial applications requiring vibration resistance and reliable positioning. The black-oxide alloy steel construction combined with Rockwell C45 hardness provides exceptional strength and corrosion resistance, while the nylon patch thread locker eliminates loosening in high-vibration environments. The headless hex drive design allows for flush mounting in confined spaces, making it ideal for precision machinery, automotive components, and manufacturing equipment where secure fastening is paramount. The cup tip ensures maximum grip on shafts and collars, preventing slippage under heavy loads and rotational forces.

Specification Summary & Compliance

This set screw features 10-24 UNC coarse threads with Class 3A fit for precision threading applications. Manufacturing complies with ASME B18.3 specifications where applicable, ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting current substance restriction requirements for industrial use.
