The 316 alloy is a molybdenum-bearing austenitic stainless steel that contains 18% chromium, 8% nickel, and 2-3% molybdenum. The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than the 304 alloy, which is especially true in pitting and crevice corrosion within chloride environments. In addition, Alloy 316 provides excellent elevated temperature tensile and stress rupture strengths, as well as outstanding weldability.
Cap Screws M12x40 A4 SS 316 912
A socket cap screw, also known as a socket head, cap screw, socket screw, or Allen bolt, is a type of cap screw with a cylindrical head and hexagonal drive hole. Socket head cap screws are commonly used in assemblies that do not provide sufficient clearance for a conventional wrench or socket.nThe head has a larger diameter than the threaded portion, this provides a positive mechanical stop when tightening the screw. Cap screws are tightened directly into a threaded or tapped hole, usually without a nut.nSocket head cap screws are typically used in machine parts, die fixturing, and clamping.nThe most basic difference between a cap screw and a bolt is the way in which these fasteners are installed. Technically, a bolt is installed by turning a nut to tighten the fastener, while a cap screw is installed by turning the head of the bolt to assemble and tighten.
