Professional Applications & Engineering Value
Engineered for demanding environments, these A286 stainless steel socket head cap screws deliver critical performance advantages where standard fasteners fail. The combination of 160,000 psi tensile strength and Class 3A UNRF fine threads creates exceptionally secure joints that resist loosening under vibration and thermal cycling. The passivated finish enhances the inherent corrosion resistance of A286 material, making these screws ideal for aerospace components, precision instruments, and industrial equipment exposed to chemicals or moisture. The hex socket drive accommodates high installation torque while the fully threaded design provides maximum engagement strength throughout the entire 5/16" length, solving common challenges with thread stripping and connection reliability in compact assemblies.
Specification Summary & Compliance
This 0-80 UNRF thread socket head cap screw maintains precision Class 3A thread fit tolerances with fine thread spacing and right-hand thread direction. Manufacturing complies with Fed. Spec. FF-S-86, NAS1351N00-5, and SAE AMS5737 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring material safety and regulatory acceptance for global industrial applications.
