Professional Applications & Engineering Value
This 8-32 thread socket head cap screw is engineered to solve critical challenges in demanding sectors like aerospace, automotive, and heavy machinery. Made from A286 stainless steel with a passivated finish, it resists oxidation and chemical exposure, ideal for environments where corrosion compromises safety. The coarse UNRC thread and Class 3A fit ensure rapid, secure engagement in high-vibration setups, reducing maintenance downtime. With a 4-inch length and partial threading, it provides optimal grip in assemblies requiring adjustable tension, while the 160,000 psi tensile strength supports heavy loads without deformation, enhancing structural integrity in critical joints.
Specification Summary & Compliance
This screw adheres to Class 3A thread fit for precise dimensional accuracy, with UNRC coarse threads and a right-hand direction. It meets ASME B18.3, NAS1352N08-64, and SAE AMS5731/5737 specifications, ensuring manufacturing consistency. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, supporting environmental and safety regulations in global supply chains.
