S-90669A338 10-32 x 1/4" 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, secure fastening ensured by Class 3A thread fit and fine UNF threads for minimal backlash
• Enhanced component protection with soft brass tip that prevents damage to shafts and mating surfaces
• Reliable installation torque through 3/32" hex drive that resists stripping under high stress
• Consistent mechanical performance with Rockwell B80 hardness balancing strength and machinability
• Space-saving headless design allowing flush mounting in confined assembly applications
• Regulatory compliance assurance meeting ASME B18.3 standards and environmental regulations

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers critical engineering solutions for precision assemblies requiring reliable positioning and locking. The 18-8 Stainless Steel material provides excellent corrosion resistance in manufacturing, automotive, and electronic equipment applications. The fine thread configuration ensures superior vibration resistance compared to coarse threads, while the brass tip eliminates galling and surface damage on precision shafts and rotating components. The headless design with hex drive enables installation in space-constrained environments where traditional fasteners cannot be used, making it ideal for set collar applications, gear positioning, and adjustable mechanism locking.
