Socket Head Screw is a special type of screw with a hexagonal internal drive built into the head. This feature distinguishes it from other screw head drive styles such as Phillips head screws, slotted head screws and flat head screw. Socket Screws are typically used in a wide range of applications including steel fabrication, machine tools and furniture manufacture as well as automotive production lines and industrial equipment.
Socket Cap Screws provide impressive clamping strength and have a finished appearance that is both discreet and neat. When compared to standard hex head bolts, socket screws provide a larger bearing surface, allowing them to support greater amounts of torque while also providing a higher level of shear and tensile strength.
A number of different designs exist, with each one intended for a specific application. Hex Socket Cap Screws are the most common and widely used of all socket cap screws. They are available in a range of sizes and lengths, ranging from 1/4 inch up to 2 inches in imperial or metric threaded fasteners.
Other types include low head socket cap screws, button head socket caps and flat head socket caps. Low head socket screws have a head height that is 50% lower than traditional socket caps, allowing them to be used in applications with limited clearance restrictions. However, they cannot withstand the same preload as standard socket caps.
Button head socket caps have a rounded head profile that makes them ideal for use in confined spaces where a squared off head might snag or scratch delicate components. They can also be used for security purposes, as they are a reliable choice where there is little or no room to fit a conventional nut or bolt. Socket Head Screw
