Professional Applications & Engineering Value
This A286 stainless steel socket head cap screw is engineered to address critical challenges in demanding sectors like aerospace, automotive, and heavy machinery. Its high tensile strength (160,000 psi) and yield strength (120,000 psi) prevent deformation under extreme loads, while the passivated finish enhances corrosion resistance in humid or chemical-exposed environments. The Class 3A thread fit with UNRC coarse threads ensures rapid assembly and reliable clamping force, reducing installation time and maintenance needs. Ideal for high-strength fastening in engines, structural frames, and precision equipment, it delivers long-term reliability where failure is not an option.
Specification Summary & Compliance
This screw adheres to Class 3A thread tolerances for precise fit, with UNRC coarse threads (1/4"-20) and a right-hand thread direction. It conforms to Fed. Spec. FF-S-86, NAS1352N4-12, and SAE AMS5737 manufacturing standards, ensuring consistent dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible sourcing and usage.
