Screws are typically inserted into components or surfaces and interact with female threads that have been threaded into the fastening surface. Drilling and tapping screws can be fastened to a surface or component without the need for a pre-drilled hole, whereas non-tapping screws necessitate a threaded pilot hole. Socket head cap screws find their utility in situations where a standard bolt or screw might prove insufficient in strength or cause excessive space consumption. Specialty shoulder screws and set screws are employed in mechanical assemblies to facilitate part rotation or securely hold rotating components in place.
