S-92695A625 4-40 x 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with 90° cone point design that bites into surfaces for maximum grip and prevents component slippage
• Exceptional durability from Rockwell C45 hardness alloy steel construction that resists wear and deformation under heavy loads
• Precision thread engagement with Class 3A thread fit ensuring tight tolerances and reliable fastening in critical applications
• Corrosion-resistant protection through black-oxide surface treatment that extends service life in demanding industrial environments
• Space-saving headless design allowing flush mounting where clearance is limited while maintaining full fastening strength
• Easy installation and removal with 0.050" hex drive that provides secure tool engagement and prevents stripping during torque application
• Industry-standard compatibility with UNC coarse threads that ensure broad interchangeability and reliable performance across equipment

Professional Applications & Engineering Value

This 4-40 UNC set screw delivers critical engineering solutions for industrial applications requiring precise component positioning and permanent fastening. The black-oxide alloy steel construction combined with Rockwell C45 hardness provides exceptional resistance to vibration loosening and material fatigue, making it ideal for machinery, automotive assemblies, and precision equipment where reliability is paramount. The 90° cone point design creates concentrated pressure points that securely lock components without damaging surfaces, while the headless configuration enables flush installation in confined spaces. The coarse UNC threads ensure quick assembly and disassembly while maintaining superior holding strength in high-stress environments, making this hex drive set screw an essential component for maintenance professionals and manufacturing engineers.
