Professional Applications & Engineering Value

These 316 stainless steel rounded head screws deliver critical corrosion protection in chemical processing, marine, and food industry applications where exposure to chlorides and acidic environments is common. The passivated finish creates an additional protective oxide layer, significantly extending service life in aggressive conditions. The 10-24 UNC coarse thread configuration provides excellent engagement in various materials while resisting cross-threading during installation. With fully threaded design and Class 2A thread fit, these fasteners ensure consistent clamping force distribution across the entire 1½" length, making them ideal for assemblies requiring uniform pressure and vibration resistance. The combination of 100,000 psi tensile strength and Rockwell B100 hardness provides reliable performance in structural applications while maintaining sufficient ductility to prevent brittle failure.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 standards with Class 2A thread fit tolerance for consistent dimensional accuracy. The 10-24 UNC coarse thread (0.19" diameter) with right-hand direction ensures proper engagement in inch-system applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance adherence. The passivated finish on 316 stainless steel provides enhanced surface protection while maintaining the material's inherent corrosion resistance properties.
