Professional Applications & Engineering Value

This 316 Stainless Steel Socket Head Cap Screw is engineered to address critical challenges in industrial fastening, where exposure to corrosive agents, high stress, and vibration are common. The passivated finish enhances the innate corrosion resistance of 316 stainless steel, making it ideal for chemical processing, marine, and food-grade equipment. Its 5/8"-11 UNC coarse threads with Class 3A fit provide excellent grip and fatigue resistance, reducing the risk of loosening in dynamic loads. The 1/2" hex drive allows for high-torque installation with standard tools, ensuring secure connections in heavy machinery, structural assemblies, and automotive applications. By combining material durability with precision threading, this screw minimizes maintenance downtime and extends service life in demanding environments.

Specification Summary & Compliance

This socket head cap screw meets precise dimensional standards, including UNC coarse threads with Class 3A thread fit for tight tolerances and reliable engagement. Manufacturing adheres to industry practices for inch-system measurements, with key specs such as 4" length, 5/8"-11 thread size, and partially threaded rod type. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted substances and suitable for use in regulated markets.
