S-92785A053 2-56 x 3/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability
• Exceptional holding power from the 90° cone point tip that bites into materials for secure, vibration-resistant fastening
• Precise thread engagement with Class 3A fit ensuring tight tolerances and reduced risk of cross-threading during assembly
• Easy installation in confined spaces using the hex drive and headless design, allowing flush mounting without protruding components
• High mechanical strength backed by Rockwell B80 hardness, providing durability under load without stripping or deformation
• Broad industry compatibility with UNC coarse threads and right-hand direction, suitable for standard industrial equipment and components
• Regulatory peace of mind through compliance with ASME B18.3, RoHS 3, and REACH, meeting strict quality and environmental standards

Professional Applications & Engineering Value

This 2-56 UNC thread set screw delivers critical performance in precision assemblies where space is limited and reliability is non-negotiable. The 18-8 stainless steel material resists oxidation and chemical exposure, extending service life in machinery, electronics, and automotive systems. Its hex headless design and cone point tip enable deep, secure fastening without head interference, effectively preventing loosening from vibrations—a common failure point in dynamic applications. The coarse thread spacing and Class 3A thread fit ensure quick installation and consistent clamp force, reducing assembly time while maintaining joint integrity. Ideal for securing gears, pulleys, and collars, this fastener solves alignment and slippage issues in high-precision engineering environments.

Specification Summary & Compliance

This set screw features a 2-56 UNC thread with 0.086" diameter and 3/16" length, manufactured to Class 3A thread fit for precise dimensional accuracy. It conforms to ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to industry and environmental standards for safe, reliable use.
