S-92313A425 1/2"-13 x 1 1/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Precise, reliable fastening ensured by Class 3A thread fit and UNC coarse threading for reduced cross-threading and secure assemblies
• Enhanced gripping power from the cup point tip, which bites into surfaces to prevent component slippage under vibration
• Easy installation and removal with the 1/4" hex drive, allowing high torque application without head protrusion
• Long-term durability supported by Rockwell B80 hardness, maintaining thread integrity and mechanical performance
• Regulatory peace of mind with compliance to ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards
• Optimized for heavy-duty use in industrial settings, thanks to the headless design and coarse thread for quick assembly

Professional Applications & Engineering Value

This 316 stainless steel set screw is engineered to address common industrial challenges like corrosion, vibration loosening, and precise alignment needs. The UNC coarse thread and Class 3A fit provide excellent engagement in soft materials or where rapid assembly is critical, reducing installation time and improving reliability. The cup point tip creates a firm bite into shafts and hubs, preventing rotational movement in machinery, automotive, and marine applications. With its hex drive and headless design, it offers a flush finish ideal for confined spaces, while the high corrosion resistance of 316 SS ensures longevity in humid or chemical-rich environments, minimizing maintenance and replacement costs.

Specification Summary & Compliance

This set screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for tight tolerances and UNC coarse threading (1/2"-13) for robust performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use. The dimensions include a 1-1/4" length, 0.5" thread diameter, and 1/4" hex drive, all manufactured to precise standards for consistent quality and reliability in demanding applications.
