Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
  • Exceptional holding power ensured by Class 3A thread fit, providing tighter tolerances and reduced risk of loosening under vibration.
  • High durability and strength from Rockwell B80 hardness, resisting wear and deformation in demanding applications.
  • Secure and efficient installation with the 3/32" hex drive, allowing for high torque application without cam-out in confined spaces.
  • Enhanced grip and positioning due to the extended tip design, improving contact and preventing component slippage.
  • Reliable performance in right-hand coarse UNC threads, facilitating quick assembly and disassembly while maintaining strong engagement.
  • Compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental responsibility.

Professional Applications & Engineering Value

This 10-24 UNC set screw is engineered to address common industrial challenges such as component misalignment and vibration-induced loosening. Crafted from 18-8 stainless steel, it offers excellent resistance to corrosion and oxidation, making it suitable for applications in machinery, automotive, and electronics where exposure to moisture or chemicals is a concern. The Class 3A thread fit and coarse thread spacing provide a precise, secure fastening that withstands dynamic loads, while the headless design and 3/32" hex drive enable flush mounting and easy access in tight spaces. The extended tip enhances gripping force on shafts or collars, reducing the need for frequent retightening and improving overall assembly integrity in industrial set screw applications.

Specification Summary & Compliance

This set screw adheres to Class 3A thread fit for high precision and consistent performance, with UNC coarse threads ensuring reliable engagement. It meets ASME B18.3 specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial uses.
