S-92311A594 5/16"-24 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 environments and extended service life
• Precise, secure fastening ensured by Class 3A thread fit for minimal backlash and reliable performance in high-vibration applications
• High torque transmission via the 5/32" hex drive, allowing for efficient installation and removal without stripping
• Excellent grip and resistance to loosening from the cup point tip, which bites into the mating surface for a firm hold
• Consistent mechanical strength with a Rockwell B80 hardness, providing durability and resistance to wear
• Reliable fine thread engagement with the 5/16"-24 UNF right-hand thread, offering improved adjustment precision
• Headless, space-saving design for applications where a flush or low-profile finish is required

Professional Applications & Engineering Value

This 18-8 stainless steel set screw is engineered to address common industrial challenges such as component slippage, corrosion-induced failure, and assembly space constraints. Its headless design and cup point provide a secure, flush mount that minimizes protrusion in machinery, automotive, and precision equipment. The UNF fine thread and Class 3A fit ensure tight tolerances, reducing the risk of vibration loosening in dynamic applications. Made from corrosion-resistant stainless steel with a hex drive for high torque application, it offers reliable performance in demanding environments, from manufacturing assemblies to outdoor fixtures, enhancing operational safety and reducing maintenance frequency.
