About Socket Head Cap Screws:

Socket Head Cap Screws are heavy duty screws made from DFARS sourced alloy steel. Manufactured in the USA , these strong externally threaded screws offer the highest strength for commercial fasteners, and are the ideal fastener where there is not sufficient space for wrenches or sockets. They are often used in machine assembly and other industrial uses where panel installation requires a smooth appearance and elimination of bulky parts.

In many assemblies, using Socket Head Cap Screws requires fewer screws as they are stronger than conventional screws. A hex key or allen wrench is used on the internal hex socket drive to install the screws into applications that do not have enough space for traditional wrenches or sockets. Alloy steel provides a reliable response to heat treatment and it is both tough and strong at high strength.
