EXTENDED GRIP RANGE FASTENER AND DRIVER Abstract of the Disclosure A fastener and driver combination in which the fastener exhibits an extended grip range thereby enabling a single fastener to be used in a wide range of applications. The fastener comprises a bolt having a head and a threaded shank receivable in an internally threaded barrel projecting from one face of the head of a nut. The nut has a driving recess in its other, outer, face. The threaded passage through said barrel is in open communication with the driving recess in said nut whereby the bolt shank can enter the driving recess when the nut is tightened on the bolt. The length of the bolt shank is substantially equal to the combined length of the nut barrel and the nut head whereby the bolt shank cannot project beyond the outer face of the nut head when the nut is tightened on the bolt. A driving tool is provided with an exterior surface complementary to the inner surface of the driving recess in the nut head. The driving tool also has a recess in the end thereof for loosely receiving the bolt shank when and if it enters the driving recess.
