S-92308A597 5/16"-18 x 1 1/2" ASME B18.6.2 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Maximum holding power ensured by the cup tip design, which bites into surfaces to prevent component slippage.
• Precise and reliable thread engagement with Class 2A thread fit, reducing the risk of cross-threading and ensuring consistent performance.
• Enhanced durability and wear resistance from Rockwell B80 hardness, maintaining integrity under repeated use and stress.
• Easy installation and removal thanks to the external square drive and coarse UNC threads, saving time in assembly and maintenance.
• Secure fastening in high-vibration applications with right-hand thread direction and coarse thread spacing for a tight, stable hold.
• Confidence in regulatory compliance by meeting ASME B18.6.2 standards, RoHS 3, and REACH, ensuring safe and approved use in industrial settings.

Professional Applications & Engineering Value

This 5/16"-18 UNC Square Head Set Screw is engineered to address common industrial challenges like component loosening and material degradation. Crafted from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it suitable for applications in moist or chemically aggressive environments, such as machinery, automotive assemblies, and outdoor equipment. The coarse thread spacing and Class 2A thread fit provide quick, secure fastening with minimal risk of stripping, while the cup tip ensures a firm grip on shafts or hubs to prevent rotational movement. Its Rockwell B80 hardness adds durability, reducing wear over time and supporting heavy-duty use in manufacturing and construction. By integrating these features, this set screw delivers reliable performance, minimizes maintenance downtime, and enhances the longevity of assembled components.
