Socket Head Cap Screws

Also called Allen head screws, socket head cap screws are a type of threaded fastener. They typically have a cylindrical head with an inset hexagon drive that can be used in conjunction with a key for tightening. Socket head cap screws have a number of benefits over other fastener types, including the ability to better tensile and yield strength compared to other screw types.

MW Components manufactures both stock and custom socket head cap screws in a variety of sizes and diameters. The majority of our socket head cap screws are available in stainless steel, although we also work with specialty alloys upon request. For more information on our in-stock selection of socket head cap screws, view our stock lists below or shop our inventory of closeout parts.
