An External Torx version exists, also known as Inverted Torx, where the screw head has the shape of a Torx screwdriver bit, and a Torx socket is used to drive it.

An external Torx screw has a projecting head in the shape of a Torx screwdriver bit (instead of a standard recessed cavity); a Torx socket is used to drive it. The external "E" Torx nominal sizing does not correspond to the "T" size (for example, an E40 socket is too large to fit a T40, while an E8 Torx socket will fit a T40 Torx bit [ 68 ] ).

[3]: 85–86 They also allow the use of angled screwdrivers and trim-head screws. The socket-headed Robertson screws are self-centering and reduce cam out. They also stop a power tool when set, and can be more easily removed if painted over, or old and rusty. [3]: 85–86 In industry, they speed up production and reduce product damage.
