ABSTRACT:
A socket having a recess in its front end fitted over a nut or bolt head, and an internal key, smaller than the recess, slidable in the socket forwardly through the socket to the exterior. The key fits in an internal socket in the nut or bolt head, and is retracted automatically in cases where there is no internal socket in the nut or bolt head. Two forms are disclosed, in one, the internal is insertable into and removed from the socket through the rear end, and in the other, through the front end. In one form, the socket can be used in the case where a nut is run down on a bolt a great distance, leaving a long extension of the bolt beyond the nut.
