S-92311A598 5/16"-24 x 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 vibration resistance due to UNF fine threads and Class 3A fit, preventing loosening under dynamic loads
• High torque transmission enabled by the 5/32" hex drive, allowing secure installation without head interference
• Reliable surface marking and secure seating with cup tip design for permanent component positioning
• Consistent mechanical performance from Rockwell B80 hardness, balancing strength and ductility
• Space-saving installation through headless design, perfect for confined assembly applications
• Long-term operational reliability with compliance to RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

This 18-8 stainless steel set screw delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The 5/16"-24 UNF fine thread configuration with Class 3A fit ensures minimal backlash and superior clamping force in precision assemblies, while the headless hex design with 5/32" drive enables installation in space-constrained applications without compromising torque capability. The cup tip provides excellent bite into shaft materials, preventing slippage in high-torque transmission systems, making it ideal for permanent positioning in machinery, automotive components, and industrial equipment requiring reliable fastening under demanding conditions.

Specification Summary & Compliance
