S-92308A544 1/4"-20 x 1 1/4" ASME B18.6.2 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments
• Exceptional torque transmission via the square head and external square drive, preventing tool slippage during installation
• Precise thread engagement with Class 2A UNC coarse threads, enabling quick assembly and secure fastening
• Enhanced holding power from the cup tip design, which bites into surfaces to prevent component movement
• Consistent mechanical performance backed by Rockwell B80 hardness, providing optimal strength without brittleness
• Broad industrial compatibility with 1/4"-20 UNC right-hand threading, matching common equipment and components
• Regulatory peace of mind through compliance with ASME B18.6.2, RoHS 3, and REACH standards

Professional Applications & Engineering Value

This 1/4"-20 UNC square head set screw delivers critical performance in demanding industrial settings where vibration resistance and positional security are paramount. The 18-8 stainless steel material inherently resists oxidation and chemical exposure, making it ideal for machinery, automotive assemblies, and outdoor equipment. Its coarse UNC threads and Class 2A thread fit ensure rapid installation with reduced cross-threading risks, while the cup tip concentrates pressure to securely lock shafts, collars, and gears without loosening. Engineered to ASME B18.6.2 specifications, it provides reliable torque-to-clamp force conversion, preventing downtime in production lines and maintenance operations.

Specification Summary & Compliance

This set screw features a 1/4"-20 UNC coarse thread with Class 2A dimensional tolerance for consistent fit. It is manufactured in compliance with ASME B18.6.2 mechanical and dimensional requirements, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global markets.
