Professional Applications & Engineering Value
This 18-8 Stainless Steel Socket Head Cap Screw is engineered to address critical challenges in machinery, automotive, and construction assemblies. Its high tensile strength (70,000 psi) and Rockwell B70 hardness prevent stripping and failure under heavy loads, while the Class 3A thread fit and coarse UNC thread reduce cross-threading risks and ensure reliable fastening in high-vibration environments. The corrosion-resistant material and hex drive design make it suitable for outdoor equipment, marine applications, and automated systems, providing long-lasting performance with minimal maintenance. By integrating ASME B18.3 standards, it delivers consistent dimensions and compatibility, streamlining procurement for industrial fastener needs.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with Class 3A fit for precise tolerance, a 3/16" hex drive, and dimensions including a 1/2" length and 3/8" head diameter. It complies with ASME B18.3 for dimensional accuracy, RoHS 3 (2015/863/EU) for restricted hazardous substances, and REACH (EC 1907/2006) for chemical safety, ensuring it meets rigorous industrial and regulatory requirements.
