Socket Head Cap ScrewsCap screws come with large cylindrical heads that have recessed hex-shaped drives. These make them suitable for applications where clearance is limited, and sockets and wrenches can't be used.

Our allen head screws are available in alloy steel, which is the strongest of all steel types. and the high tensile strength provides excellent resistance to galling, fatigue and wear.
Allen Head Screw ApplicationsStainless steel socket head cap screws are generally the best screw choice for applications with limited access. Allen head screws can be efficiently adjusted with tools from a standard socket set to allen wrenches, which require very little clearance around the fastener.
