S-92311A628 3/8"-16 x 1 1/2" 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
• Exceptional thread precision with Class 3A fit ensuring reliable, vibration-resistant fastening in critical assemblies
• Optimized torque transmission through the 3/16" hex drive design, preventing tool slippage during installation
• Enhanced grip strength from the cup point tip that creates permanent seating in shaft collars and pulleys
• Consistent mechanical performance backed by Rockwell B80 hardness for maintained clamping force under load
• Broad compatibility with UNC 3/8"-16 coarse threads, matching standard components across industries
• Regulatory confidence through full compliance with ASME B18.3, RoHS 3, and REACH standards

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 18-8 stainless steel set screw delivers reliable performance in machinery, automotive, and aerospace assemblies. The UNC 3/8"-16 coarse thread with Class 3A fit provides superior engagement in threaded holes, resisting loosening from vibration—a common failure point in rotating equipment. The hex headless design allows flush mounting in confined spaces, while the cup point bites securely into shafts, preventing axial movement of gears and couplings. With Rockwell B80 hardness, it maintains structural integrity under repeated stress, making it ideal for permanent set applications where disassembly is infrequent.

Specification Summary & Compliance

This 1-1/2" length set screw features UNC coarse threads with Class 3A thread fit for precision tolerance, manufactured to ASME B18.3 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The right-hand thread direction and 3/16" hex drive conform to industry-standard installation practices.
