Abstract: A socket holder for a plurality of socket wrench sockets has studs projecting from a top surface, each of the studs being sized and shaped closely uniquely to engage a particular socket so that the socket on a stud will not be accidentally dislodged, and the stud can be used to measure a nut or the head of a bolt before the socket is employed. The studs are accompanied by indicia of size. Preferably, the indicia may be tactilely read.
