A quad wrench has a head including an internal guide, first and second crowns separated by said internal guide, each of said first and second crowns having a plurality of interior faces, and 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 a shank connected to said head. 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 each bolt receiving space of the quad wrench is configured to correspond to two different certain sizes of bolts.
