  • Patent number: 5904081
    Abstract: A threaded fastener and mating driver system is used to apply a uniform torque to the entire fastener body and thereby facilitate removal of stuck fasteners. The driver tool is a two stage driver with one stage driving the inner bore of the fastener and the second stage driving the fastener head. The two driver stages are linked via a series of pins, each pin acting as an individual lever, such that the two drivers apply torque equally to the fastener. The entire driver assembly is housed in a block which can be attached to a standard ratchet or driving tool. The fastener is designed to be installed using a single stage screwdriver and normally has a foil seal covering the bore drive portion of the fastener. If the fastener becomes stuck, the foil seal is broken and the two stage drive system, including a bore driver and a screw head driver, is inserted into the fastener to effect additional removal torque.
