Other names for an Allen key screw include Allen bolt, socket screw and socket head cap screw. These fasteners have a hexagonal drive hole sunken into the head.

To tighten this type of bolt, you will need to use a compatible Allen wrench. Bolts look similar to hex head cap screws. The main difference between them has to do with how you install them.
