Professional Applications & Engineering Value

This 1/2"-13 UNC set screw delivers critical engineering solutions for industrial applications requiring permanent component positioning. The Black Oxide Alloy Steel construction combined with Rockwell C45 hardness provides exceptional resistance to loosening under vibration and impact loads, making it ideal for heavy machinery, automotive assemblies, and power transmission systems. The extended tip design ensures deeper penetration into shaft keyways and collars, preventing slippage in high-torque environments. With its Class 3A thread fit and coarse thread spacing, this headless set screw offers superior holding strength while accommodating minor material variations in manufacturing applications. The 1/4" hex drive facilitates quick installation and removal, reducing maintenance downtime in production environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 3A thread fit tolerance for superior engagement. Thread specifications conform to 1/2"-13 UNC coarse thread standards with extended tip dimensions maintained within tight tolerances (tip diameter: 0.343" ±0.009", tip length: 0.13" -0.005" to 0"). Full compliance with ASME B18.3 mechanical specifications, RoHS 3 (2015/863/EU) environmental directives, and REACH (EC 1907/2006) chemical substance regulations for industrial applications worldwide.
