Torq-Set® Insert Bits, #10, 5/16 in drive, Hex, Spring

Torq-Set® Insert Bits are 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 and 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.
