Key Features & Benefits at a Glance
- Maximum holding power with Class 3A thread fit ensuring precise, vibration-resistant connections in demanding applications
- Superior corrosion resistance from Black-Oxide finish on Alloy Steel, extending service life in harsh industrial environments
- Enhanced grip and alignment with 118° cone point design that bites into materials for secure positioning
- High-strength durability backed by Rockwell C45 hardness, maintaining structural integrity under heavy loads
- Easy installation and removal using standard 1/4" hex drive tools, reducing assembly time and labor costs
- Reliable coarse threading (UNC) for quick engagement and reduced cross-threading risks in production settings
- Industry-standard compliance meeting ASME B18.3 specifications for consistent quality and interchangeability
Professional Applications & Engineering Value
This 1/2"-13 UNC set screw delivers critical engineering solutions for industrial assemblies requiring permanent component positioning. The Black-Oxide Alloy Steel construction provides exceptional corrosion protection while maintaining Rockwell C45 hardness for load-bearing applications. The 118° cone point creates concentrated surface pressure that prevents slippage in shafts, collars, and gears—solving common rotational loosening issues. With coarse thread spacing and Class 3A fit, it ensures rapid installation in manufacturing lines while maintaining precision alignment. Ideal for heavy machinery, automotive components, and power transmission systems where vibration resistance and reliable fastening are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for superior dimensional accuracy. Features UNC coarse threads (1/2"-13) with right-hand direction and 0.5" thread diameter. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Meets material standards per ASTM F912 for consistent performance in industrial fastener applications.
