Professional Applications & Engineering Value

These 316 stainless steel hex head screws deliver exceptional performance in demanding industrial environments where corrosion resistance and mechanical reliability are critical. The 5/16"-24 UNF fine thread configuration provides superior vibration resistance compared to coarse threads, making them ideal for machinery, equipment assembly, and structural applications subject to dynamic loads. The partially threaded design concentrates the thread engagement where maximum clamping force is needed, while the external hex drive ensures secure tool engagement even in high-torque applications. With their 70,000 psi tensile strength, these fasteners maintain integrity under significant stress, while the Class 2A thread fit guarantees consistent performance across multiple installations and disassemblies.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 standards with Class 2A thread fit tolerance for precision fastening applications. The 5/16"-24 UNF fine thread configuration ensures optimal performance in vibration-prone environments. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these screws suitable for use in regulated industries and international markets. The 316 stainless steel composition provides superior corrosion resistance compared to standard grades, while maintaining 70,000 psi tensile strength and Rockwell B70 hardness for demanding mechanical applications.
