S-92313A712 1/2"-13 x 1" 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
• Exceptional thread precision with Class 3A fit ensures tight, secure fastening with minimal backlash in high-vibration applications
• High mechanical strength from Rockwell B80 hardness provides reliable, long-term holding power under heavy loads
• Secure anti-loosening grip thanks to the cup point tip design that bites into surfaces, preventing component slippage
• Easy installation in confined spaces with the headless and 1/4" hex drive design, allowing flush mounting and tool accessibility
• Wide industrial compatibility with UNC coarse threads and right-hand direction, fitting standard components and speeding assembly
• Regulatory peace of mind through compliance with ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 1/2"-13 UNC Class 3A set screw delivers critical reliability in machinery, automotive, and marine applications. The 316 Stainless Steel material excels in corrosive environments, resisting acids and salts, while the hex headless design and cup point provide a flush, non-protruding fastening solution that digs securely into shafts and collars. This prevents rotational slip and maintains alignment under high torque and vibration. With coarse thread spacing and right-hand thread direction, it ensures quick installation and robust performance in heavy-duty assemblies, reducing maintenance downtime and enhancing operational safety.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including UNC thread type with Class 3A thread fit for superior tolerance control. It meets ASME B18.3 specifications for consistency and reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial and international markets.
