S-92505A575 5/16"-18 x 5/16" ASME B18.3, ASTM F912 Set Screws

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 thanks to Black Oxide finish on Alloy Steel, extending service life in harsh industrial environments
• Easy installation and removal with 5/32" hex drive design, allowing high torque application without stripping
• Enhanced fastening performance through extended tip design that provides better engagement and prevents component slippage
• Exceptional durability with Rockwell C45 hardness maintaining structural integrity under heavy loads and repeated use
• Reliable coarse threading using 5/16"-18 UNC specification for quick assembly and superior resistance to loosening
• Headless construction enabling flush mounting in space-constrained applications while maintaining full fastening strength

Professional Applications & Engineering Value

This 5/16"-18 UNC set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The Black Oxide Alloy Steel construction combined with Class 3A thread fit addresses common industrial challenges of component slippage and thread wear in high-stress assemblies. The extended tip design provides concentrated point loading for superior grip on shafts, collars, and pulleys, while the coarse UNC threading ensures rapid installation in production environments. Ideal for machinery, automotive, and manufacturing applications requiring headless fasteners that maintain precise alignment without protruding components.
