Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 Stainless Steel construction for long-lasting performance in harsh industrial environments
  • Maximum holding power and vibration resistance achieved through Class 3A thread fit precision and coarse UNC threading
  • Extended tip design provides deeper penetration and superior grip on mating components
  • Headless configuration with 1/16" hex drive allows for flush installation in confined spaces
  • Exceptional mechanical strength with Rockwell B80 hardness for reliable performance under heavy loads
  • Right-hand thread direction ensures standard installation compatibility across industrial applications
  • Regulatory compliance assurance meeting both RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

This 6-32 UNC set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and reliable clamping force are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in demanding environments, while the extended tip design ensures positive seating and prevents loosening in dynamic applications. The Class 3A thread fit guarantees precise engagement with mating components, making it ideal for precision equipment, automotive assemblies, and industrial machinery where headless fasteners are required for space-constrained applications. The 1/16" hex drive facilitates secure installation while maintaining the low-profile advantage of set screws in rotating components and shaft collars.

Specification Summary & Compliance

This precision fastener features 6-32 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and engagement. Manufactured to ASME B18.3 specifications, the set screw maintains critical tolerances including tip diameter (0.092") and tip length (0.038") with precise manufacturing control. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets while meeting the highest quality standards for industrial set screws.
