Professional Applications & Engineering Value

This A286 stainless steel socket head cap screw is engineered to address critical challenges in demanding environments like aerospace, automotive, and heavy machinery. Its high tensile strength (160,000 psi) and yield strength (120,000 psi) provide a safety margin against dynamic loads and vibrations, preventing joint failure in structural applications. The passivated finish on the UNRC coarse thread enhances corrosion resistance, which is vital for outdoor or chemically exposed settings. With a partially threaded design and Class 3A thread fit, it ensures precise clamping force distribution, reducing stress concentration. Ideal for high-performance assemblies, this screw meets rigorous standards like ASME B18.3, offering reliability in critical fastening tasks where durability and compliance are non-negotiable.
