- Precise thread engagement with Class 3A fit ensuring reliable assembly and reduced risk of cross-threading
- High torque capability via the 1/4" hex drive that prevents tool slippage and enables efficient installation
- Enhanced durability from Rockwell B80 hardness, maintaining structural integrity under repeated stress
- Industry-standard compliance meeting ASME B18.3 specifications for consistent quality and interchangeability
- Environmental safety with RoHS 3 and REACH compliance, ensuring safe use in regulated applications
Professional Applications & Engineering Value
This 1/2"-13 UNC set screw delivers critical engineering solutions for industrial applications requiring permanent, high-strength fastening. The 18-8 stainless steel material provides excellent corrosion resistance in machinery exposed to moisture or chemicals, while the cup point tip creates permanent seating by indenting into shafts and collars to prevent rotational slippage—ideal for securing gears, pulleys, and couplings. The Class 3A thread fit and coarse thread spacing enable quick assembly with minimal galling, and the headless design allows flush mounting in confined spaces. These features make it particularly valuable in automotive, manufacturing, and heavy equipment where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
This set screw maintains Class 3A thread tolerance per UNC standards with 1/2"-13 coarse threading and 0.5" diameter for precise fit. Manufacturing follows ASME B18.3 specifications for dimensional consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
