S-91375A961 2-64 x 3/32" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating that protects against rust and extends service life in harsh environments
• Exceptional holding power from the cup point tip design that bites into materials for secure, vibration-resistant fastening
• Precise thread engagement with Class 3A fit ensuring tight tolerances and reliable performance in critical assemblies
• High-strength durability from Rockwell C45 hardened alloy steel construction that withstands heavy loads and repeated use
• Space-saving headless design allowing flush mounting where clearance is limited without compromising functionality
• Easy installation and removal with standardized 0.035" hex drive that provides secure tool engagement and prevents stripping
• Industry-standard compliance meeting ASME B18.3, ASTM F912, RoHS 3, and REACH requirements for quality assurance

Professional Applications & Engineering Value

This 2-64 UNF Class 3A black-oxide alloy steel set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The fine thread spacing and right-hand UNF thread type provide superior clamping force in precision assemblies, while the cup point tip creates permanent seating that prevents component slippage under dynamic loads. The headless design with 0.035" hex drive enables installation in confined spaces typical of machinery, automotive components, and electronic enclosures. The black-oxide surface treatment offers essential corrosion protection for industrial environments where moisture and chemicals are present, making these set screws ideal for permanent fastening applications requiring reliable, long-term performance.
