Professional Applications & Engineering Value
Engineered for maximum reliability, this 316 Stainless Steel Socket Head Cap Screw is the ideal solution for applications where failure is not an option. Its passivated finish significantly enhances its natural resistance to chlorides and acidic environments, making it perfect for marine, chemical processing, and food-grade equipment. The Class 3A thread fit and UNC coarse thread design provide superior vibration resistance and faster assembly compared to fine-thread alternatives, reducing installation time and maintenance needs. The combination of high tensile strength and Rockwell B70 hardness ensures that these partially threaded fasteners maintain clamp load under extreme stress, providing long-term integrity for heavy-duty machinery, automotive assemblies, and critical structural frameworks.
Specification Summary & Compliance
This Socket Head Cap Screw adheres to the UNC thread standard with a precise Class 3A thread fit. Key dimensional specifications include a 5/16"-18 thread size, a 1 3/4" length, and a 1/4" hex drive. The product is manufactured to be fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for use in regulated markets.
