A combined slotted and Robertson drive screw found in electrical power equipment and distribution equipment. The design allows for higher torque application with reduced camming, slipping out and damaging the fastener. [63] The ECX drive is not compatible with older combination Phillips and slotted head screws. [64] Although Milwaukee Electric Tool holds the trade name ECX, their marketing materials do not tell what type of screw head ECX is designed to fit. [50] Clutch [ edit ] Hi-Torque slot drives were designed by Alcoa Fastening Systems, for situations where very high torque is needed, along with the ability to repeatedly install and remove the fastener. [7] The design features curved walls, unlike the straight-walled slot drive.

A U-drive screw has a helical thread with an angle acute enough to be driven by a hammer or pressure from an arbor press, and thus has a domed head with no means of turning it. [92] These are most frequently driven into plastics with a pre-drilled pilot hole.

Triple-square fasteners are referred to as "spline" in the UK. This is potentially confusing if looking for the more unusual 12-spline flange type. While they are distinguished under close inspection by the angle at the tip of each of the 12 points (with a 90° angle on the XZN, instead of 60°) the general similarity and ability to insert the wrong tool can cause damage to the head.
