S-92311A072 2-56 x 1/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Precise thread engagement with Class 3A thread fit ensuring reliable, vibration-resistant fastening
• Enhanced torque transmission through hex drive design, preventing tool slippage during installation
• Secure component positioning with cup point tip that bites into surfaces for permanent alignment
• Optimized for high-strength applications featuring Rockwell B80 hardness for excellent durability
• Standardized compatibility with UNC coarse threads and right-hand direction for easy replacement
• Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards

Professional Applications & Engineering Value

This 2-56 UNC set screw delivers critical engineering solutions where space constraints and corrosion resistance are paramount. The 18-8 stainless steel composition provides exceptional protection against oxidation and chemical exposure in manufacturing equipment, automotive assemblies, and electronic enclosures. The hex headless design allows flush mounting in confined spaces while the cup point creates permanent seating by indenting into shaft materials. With coarse thread spacing and Class 3A thread fit, it maintains clamping force under vibration, making it ideal for precision instruments, machinery adjustment mechanisms, and permanent component fixation where disassembly isn't required.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with UNC thread form and Class 3A thread fit for precision tolerance. The 0.086" thread diameter with coarse spacing ensures rapid installation. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. Rockwell B80 hardness provides consistent performance across industrial applications.
