Power Drive Screwdriver Bits for Torq-Set® Recess Fasteners from MRO Tools are used for a cruciform screw drive often seen in torque-sensitive applications which are common in the aerospace industry and automotive repair sector. The Torq-Set® recess is similar in appearance to a Phillips drive in that it has a cross with 4 arms. In Torq-Set® screw heads the arms of the cross 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-head screwdriver will not fit the head. The Torq-Set® screw recess is commonly used in aerospace applications.
