Cap and machine screws are used to clamp machine parts together, either when one of the parts has a threaded hole or in conjunction with a nut. These screws stretch when tightened, and the tensile load created clamps the parts together.

Socket head cap screws, which are also known as allen head screws are stock items at Lightning Bolt in many materials sizes. These screws come with a hexagonal cross-section socket in the head and require an allen wrench or hex key to drive them into material and secure them into a structure.
