- 23 - BOX END WRENCH ABSTRACT OF THE DISCLOSURE Conventional multi-point box end wrenches or ring wrenches are broached completely therethrough so that when used on a bolt head or nut spaced above a sur- face, the wrench can slide down clear of the bolt head or nut and thus slip as pressure is being applied thereto. Also, it is difficult to ensure that the full depth of the wrench is engaged upon the bolt head or nut and that the plane of the wrench head is substantially parallel with the plane of the bolt head or nut. In the present invention, the broaching terminates spaced from the upper side of the blank from which the wrench is formed thus defining a retaining shoulder which rests on the upper surface of the bolt head or nut so that the wrench cannot slip downwardly thus maintaining an aligned engagement of the wrench with the bolt head or nut yet at the same time permitting the member, such as a stud, upon which the nut is engaged, to pass clear through the wrench head without interference to the threads of the stud, as the nut is being manipulated by the wrench.
