- Exceptional corrosion resistance thanks to 18-8 stainless steel construction, ideal for harsh industrial environments
- Precise Class 3A thread fit ensures tighter tolerances and more reliable fastening than standard commercial grades
- High-strength performance with Rockwell B80 hardness providing excellent durability under mechanical stress
- Easy installation and removal using standard 1/4" hex key tools without requiring head clearance
- Coarse UNC threading enables faster assembly and reduced cross-threading risk in production environments
- Full regulatory compliance meeting ASME B18.3 specifications and environmental standards including RoHS 3 and REACH
Professional Applications & Engineering Value
This 1/2"-13 UNC Class 3A set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for demanding environments including manufacturing equipment, automotive assemblies, and marine applications. The hex headless design allows installation in confined spaces while the cup point creates deep indentation in shaft components, preventing slippage under extreme rotational forces. With coarse UNC threading and Class 3A fit, this set screw ensures rapid assembly with precision alignment, reducing installation time while maintaining the highest fastening integrity for critical machinery components.
Specification Summary & Compliance
This set screw features 1/2"-13 UNC coarse threading with Class 3A thread fit for precision engagement, measuring 1-1/4" in length with 0.5" thread diameter. Manufactured to ASME B18.3 specifications and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The 18-8 stainless steel material achieves Rockwell B80 hardness for consistent mechanical performance across industrial applications.
