FASTENER HEAD AND COMPLEMENTARY DRIVER

摘要

A fastening system comprising a driver tool bit and a complementary fastener head is provided. The coupling between the driving end of the driver tool bit and the fastener head occurs via at least one protruding ledge located on the driving end, and a cavity in the fastener head shaped and sized to receive the ledge upon a rotation of the vertical Y axis (e.g. lengthwise or along a longitudinal axis) of the inserted driving end. More particularly, the cavity of the fastener incorporates an overhang which is configured to mate with the protruding ledge of the driving end of the driver tool bit, resulting in an enhanced connection during insertion or removal of the fastener from a work piece, without requiring the application of longitudinal axis pressure directed towards the work piece.

主权项

1. A fastener for receiving a driver tool bit having one or more protrusions at a driving end, the one or more protrusions tapering towards a tip of the driving end, the tip having a surface area oriented perpendicularly to the longitudinal axis of the driver tool bit, the one or more protrusions extending transversely to a longitudinal axis of the driver tool bit, the fastener comprising:
(a) a head having a receiving cavity and at least one slot defining a surface of said receiving cavity, for receiving the tip and the one or more protrusions; and (b) at least one overhang located adjacent to the slot and extending transversely therefrom over the receiving cavity, the overhang configured for directly engaging and retaining one of said one or more protrusions within the cavity while the fastener is being fastened or unfastened, and wherein the receiving cavity is further defined by a floor configured to mate with the tip of the driver tool bit, the floor having a surface area which substantially corresponds to the surface area of the tip of the driver tool bit; and wherein the receiving cavity is further defined by sidewalk that extend between the floor and the one or more overhangs, said sidewalk circumferentially enclosing the floor and configured to mate with the one or more protrusions of the driver tool bit.
