Professional Applications & Engineering Value
Engineered for critical applications, these 8-32 socket head cap screws in A286 stainless steel address common industrial challenges such as thermal expansion and corrosive exposure. The passivated finish enhances surface durability, preventing oxidation in humid or chemical-laden environments. With a Rockwell C33 hardness and 160,000 psi tensile strength, they provide robust clamping force in aerospace assemblies, heavy machinery, and high-temperature systems. The UNRC coarse thread and Class 3A fit ensure quick installation and secure fastening, minimizing loosening under dynamic loads. Ideal for industrial fasteners requiring precision and longevity, these screws deliver consistent performance where failure is not an option.
Specification Summary & Compliance
This screw features precise Class 3A thread fit per UNRC standards, with a diameter of 0.164" and coarse thread spacing. It meets stringent specifications including Fed. Spec. FF-S-86 (referencing NAS1352N08-4) and SAE AMS5737 for material and manufacturing consistency. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures environmental safety and regulatory adherence for global supply chains.
