S-94495A235 10-32 x 1/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Permanent vibration resistance with Nylon Patch thread locker that maintains secure fastening in high-stress environments
• Exceptional temperature stability from -70° to 250°F for reliable performance in extreme operating conditions
• Superior thread precision with Class 3A fit ensuring tight tolerances and reduced risk of cross-threading during installation
• Enhanced corrosion protection through Black-Oxide coating on alloy steel, extending service life in industrial settings
• High-strength durability with Rockwell C45 hardness providing excellent resistance to wear and deformation
• Secure hex drive installation using a 3/32" key for precise torque application without head protrusion in confined spaces
• Industry-standard compliance meeting ASME B18.3 specifications for consistent quality and interchangeability

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers critical engineering solutions for applications requiring permanent, vibration-resistant fastening. The Nylon Patch locking technology embedded in the fine threads creates consistent friction that prevents loosening under dynamic loads, eliminating the need for additional locking hardware. Manufactured from black-oxide alloy steel with Rockwell C45 hardness, it withstands mechanical stress while the headless hex drive design allows flush mounting in precision assemblies. Ideal for securing gears, pulleys, and collars in machinery, automotive, and aerospace systems where temperature fluctuations and continuous operation demand reliable thread retention without maintenance interventions.

Specification Summary & Compliance

This set screw features 10-32 UNF fine threads with Class 3A fit for precision engagement, manufactured to ASME B18.3 standards. The black-oxide surface treatment on alloy steel provides corrosion resistance, while the 1/4" length and 3/32" hex drive ensure consistent installation. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets environmental and safety requirements for industrial use worldwide.
