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. The high-strength A286 material combined with a passivated finish resists oxidation and chemical exposure, making it ideal for environments where corrosion could compromise integrity. The Class 3A UNRC coarse thread ensures rapid assembly and robust holding power, while the partially threaded shank concentrates stress effectively, reducing the risk of fatigue failure. By integrating ASME B18.3 and other stringent standards, this fastener delivers reliable performance in high-temperature and high-load applications, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This screw features a 1/4"-20 thread size with Class 3A fit and coarse thread spacing for precise engagement. It meets ASME B18.3, NAS1352N4-28, SAE AMS5731, and SAE AMS5737 specifications, ensuring dimensional accuracy and manufacturing consistency. Additionally, it is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, supporting environmental and safety regulations for global industrial use.
