Threaded fastener driver

The combination of a driver head and a pre-wired threaded fastener assemblage, comprising:

• (1) said driver head comprising:
• (a) a shaft, said shaft including a top end, a bottom end, a sidewall connecting said top and bottom ends, and an axis passing through both said top and bottom ends;
• (b) a kerf extending transversely and axially of said shaft and including said axis, said kerf (i) opening through said top end, (ii) having an axially extending portion with a relatively narrow width throughout most of its diametrically extending dimension, and (iii) having an axially extending portion with a tapered recess opening through one portion of said sidewall, said axially extending tapered recess defining an included angle;
• and
• (c) a blind recess extending transversely and axially of said shaft, said blind recess including said axis and opening only through said top end, and said blind recess intersecting said kerf;
• (2) said pre-wired threaded fastener assemblage being fit into said driver head, said assemblage comprising:
• (a) a threaded fastener having screw threads at one end and a generally planar profile at the other end, said planar profile being fit into said blind recess;
• and
• (b) a wire attached to said planar profile, said wire including a wrap which is side-wrapped to form a loop offset from the major lineal direction of said wire, said wrap being fit into said tapered recess;
• and
• (3) means connected to said driver head for rotating said driver head.

A driver head for a threaded fastener, comprising:

• a cylindrical shaft, said shaft including a top end, a bottom end, a sidewall connecting said top and bottom ends, and an axis passing through both said top and bottom ends;
• a kerf extending transversely and axially of said shaft and passing through said axis, said kerf opening through said top end and having a relatively narrow width;
• a chordal surface extending axially from said top end and intersecting said kerf substantially orthogonally, said surface being the result of the removal of an axially extending chordal segment from said cylindrical shaft;
• and
• an elongated blind recess extending transversely and axially of said shaft, said blind recess opening only through said top end, passing through said axis, and intersecting said kerf.
