Professional Applications & Engineering Value

This 5/16"-18 UNC set screw delivers exceptional engineering value through its specialized Black-Oxide 12L14 Steel construction and removable swivel tip design. The combination addresses critical industrial challenges including component misalignment, vibration-induced loosening, and corrosion in machinery applications. The coarse thread configuration ensures rapid installation in production environments while maintaining maximum holding power for securing gears, pulleys, and collars onto shafts. The headless design with hex drive facilitates installation in confined spaces where traditional fastener heads would interfere with adjacent components. These features make it particularly valuable for manufacturing equipment, automotive assemblies, and industrial machinery where reliable, long-term fastening solutions are essential.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC coarse thread specification (5/16"-18). The 4-7/16" length provides extended reach for deep-set applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial markets. The right-hand thread direction follows industry-standard installation practices for consistent performance across applications.
