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.

Abstract: An easy to install, reliable, and portable assistance summoning device that displays a need for assistance through interchangeable reflective symbols and letters, and more particularly to a banner like device that is temporarily attachable to vehicles such as cars, trucks, motorcycles, boats, campers, and aircraft. The banner like device is made of a light weight, flexible, and foldable sheet of material to allow compact storage of the device. The sheet of material having at least two support rods to maintain the banner in an unfurled position. The support rods may also be made of magnetic material to allow attachment of said banner to metallic surfaces. Each support rod having a durable elastic band attached to each respective end thereof, whereby said elastic bands may be attached to protruding elements of a surface to maintain the device in an extended position.
