Key Features & Benefits at a Glance

  • Enhanced vibration resistance with a green nylon 6/6 plastic tip that prevents loosening under dynamic loads
  • Superior corrosion protection from the black-oxide finish on alloy steel, extending service life in harsh environments
  • Precise thread engagement with Class 3A fit for maximum holding power and reliable fastening in critical assemblies
  • Wide temperature tolerance of the nylon tip (-50° to 250°F) ensuring performance in varied operating conditions
  • Easy installation and removal using a standard 3/32" hex drive, reducing assembly time and tool wear
  • Headless design for flush mounting in confined spaces without protruding components
  • Compliance with industry standards including ASME B18.3, ensuring consistent quality and interchangeability

Professional Applications & Engineering Value

This 10-32 UNF set screw with Class 3A thread fit and fine thread spacing delivers exceptional clamping force for precision machinery, automotive components, and electronic enclosures. The black-oxide alloy steel construction resists rust and wear, while the nylon 6/6 plastic tip eliminates marring on shafts and gears, preventing damage to expensive parts. Its headless hex drive design allows for secure fastening in tight spaces, making it ideal for adjustable assemblies and permanent installations where vibration resistance is critical. Fully compliant with RoHS 3 and REACH regulations, it meets stringent environmental and safety requirements for global industrial supply chains.

Specification Summary & Compliance

This set screw features a 10-32 UNF thread with Class 3A precision tolerance for tight fit and high strength. It adheres to ASME B18.3 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The right-hand thread direction and 3/8" length provide consistent performance in industrial applications requiring reliable, repeatable fastening solutions.
