Socket head cap screws are used for applications with limited space. They have cylindrical head and internal wrenching features, mostly hexagon socket, that allow them to be used in locations where externally wrenched fasteners are not desirable. They are used for critical vehicle applications, machine tools, tools and dies, earth moving and mining machinery, and a wide range of engineering applications. The most important reasons for the increasing use of socket head cap screws in industry are safety, reliability and economy.
There are also many advantages of socket head cap screws over traditional screws. As compared to ordinary fasteners, less socket screws of the same size can achieve the same clamping force in a joint. As fewer screws are required for a given job, fewer holes are required to be drilled and tapped. There is weight reduction as fewer screws are used. There will also be a weight reduction on account of the smaller size of the component parts since the cylindrical heads of socket screws need less space than hex heads and require no additional wrench space. Another feature is that forged heat-treated alloy examples are high strength fasteners intended for the most demanding mechanical applications, with special alloy formulations available that are capable of maintaining strength at temperatures in excess of 1000 degrees F.
