- Regulatory compliance assurance meeting ASME B18.3 specifications for quality and safety
Professional Applications & Engineering Value
This 9/16"-12 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 vibration loosening and environmental factors, making it ideal for heavy machinery, automotive assemblies, and precision equipment. The headless design with hex drive enables flush mounting in confined spaces while the cup tip creates superior gripping action without damaging shaft surfaces. These industrial set screws maintain positional integrity under extreme operational stresses, solving common challenges of component slippage and alignment loss in right-hand thread applications across manufacturing and maintenance sectors.
Specification Summary & Compliance
This set screw features precise Class 3A thread fit with UNC coarse thread spacing (9/16"-12) and 1-1/4" length. Manufactured to ASME B18.3 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment on alloy steel provides additional corrosion protection while maintaining dimensional accuracy per industrial standards.
