Zephyr Torq-Set Screwdriver Bits
Torq-Set® is a 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 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 drive is commonly used in aerospace applications.
