Professional Applications & Engineering Value

This 316 Stainless Steel Socket Head Cap Screw is engineered to solve critical challenges in industrial settings where corrosion, high stress, and precise fit are paramount. The 1/4"-20 UNC coarse thread with a Class 3A fit provides excellent resistance to loosening under vibration, making it ideal for machinery, automotive, and marine applications. The passivated finish on the 316 stainless steel significantly enhances its ability to withstand corrosive agents, acids, and saltwater environments. With a 70,000 psi tensile strength and Rockwell B70 hardness, it maintains integrity under heavy loads. The hex drive design ensures high torque application without stripping, and the partially threaded shank offers design flexibility for pinned or sliding components. This screw delivers reliable performance in industrial assembly, ensuring long-term operational safety and reducing maintenance costs.
