Claim:
A quad wrench comprising: (a) a head comprising (i) an internal guide, (ii) first and second crowns separated by said internal guide, each of said first and second crowns comprising (A) a plurality of interior faces consisting of a first group of four interior faces generally identical to one another, a second group of two interior faces generally identical to one another but generally not identical to the interior faces of the first group, and a third group of two interior faces that are generally identical to one another but generally not identical to the interior faces of the first or second groups, (B) first and second bolt receiving spaces, each bolt receiving space being at least partially defined by an outer surface of said internal guide and some of said plurality of interior faces, and (C) ten corner sections joining said interior faces, said ten corner sections consisting of: (I) a first group of five corner sections generally identical to one another, wherein each corner section of said first group of corner sections comprises two curved faces joined by a planar face, (II) a second group of three corner sections generally identical to one another but generally not identical to the corner sections of the first group, wherein each corner section of said second group of corner sections comprises two curved faces joined by a planar face (III) a third group of two corner sections generally identical to one another but generally not identical to the corner sections of the first or second groups, wherein each corner section of said third group of corner sections comprises a curved face and a planar face; and (b) a shank connected to said head; (c) wherein (i) each bolt receiving space of each crown is configured to correspond to both a first certain size of bolt and a second certain size of bolt such that a bolt of either certain size received in the bolt receiving space can be rotated when force is applied to the shank, and (ii) each bolt receiving space of the quad wrench is configured to correspond to two different certain sizes of bolts.
