ABSTRACT:
A driver for securing pre-wired threaded fasteners to the ceiling of a building structure includes a driver head, a pre-wired fastener held by the driver head, and a telescoping pole connected to the driver head. The driver head is a solid, cylindrical rod or shaft having a kerf opening through the top of the shaft and extending axially therefrom, the kerf extending either partially or completely across the diameter of the shaft. The kerf includes a tapered recess opening axially through one sidewall of the shaft. A blind recess shaped to receive the flat head of a threaded fastener also opens through the top of the shaft and intersects the kerf substantially orthogonally. The threaded fastener is pre-wired with a wire which has a closed loop at one end, the loop being off-set from the major lineal direction of the wire. When the head of the threaded fastener is fit into the blind recess, the wrap of the wire is loosely constrained against lateral motion by the tapered recess. A hollow telescoping pole has at least one aperture in a sidewall, the aperture positioned such that the free end of the wire can be inserted into the hollow interiior of the pole to confine the free end against spinning around the pole when the pole is rotated.
