A set of torq-set bits

Torq-set is a Cruciform cruciform screw drive used in torque-sensitive applications. The Torq-set head is similar in appearance to a Phillips drive in that it has a cross with 4 arms. In Torq-set however, the lines are offset from each other, so they do not align to form intersecting slots across the top of the head. Because of this, a regular Phillips or flat-blade screwdriver will not fit the head. It is used in starfleet and aerospace applications.

History[edit | edit source]

The Torq-set system was originally developed on Earth in the late 20th-century by the Phillips Screw Company which owned the name and produced the fasteners. It use for example by Boeing, Lockheed, General Dynamics, Airbus, Embraer, and Bombardier Inc.[1]

The applicable standards that govern the Torq-set geometry are National Aerospace Standard NASM 33781 and NASM 14191 for the ribbed version. The ribbed version is also known as ACR Torq-set.[2]
