Professional Applications & Engineering Value

This 18-8 stainless steel flanged socket head cap screw is engineered to address common industrial challenges such as corrosion, high-stress fatigue, and assembly precision. The UNC coarse thread with Class 3A fit ensures quick, secure fastening in applications like heavy machinery, automotive assemblies, and structural frameworks, where vibration resistance and repeatable disassembly are critical. The flange provides a larger bearing surface, reducing surface pressure and preventing loosening under dynamic loads. Its partially threaded design allows for precise clamping in specific grip lengths, making it ideal for industrial socket head bolt uses in equipment requiring robust, corrosion-resistant fasteners that maintain integrity in demanding conditions.

Specification Summary & Compliance

This fastener adheres to UNC coarse thread standards with a Class 3A thread fit for high precision, ensuring tight tolerances and reliable performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from restricted hazardous substances. Manufactured with a right-hand thread direction and partially threaded rod type, it is suitable for various industrial applications requiring consistent dimensional accuracy and environmental responsibility.
