Abstract: A holder for retaining individual hexagonal wrenches of a set of the type known as Allen wrenches. The holder is in the form of a cylindrical member fitted with a plurality of through parallel transverse wrench holes, each wrench hole of the size to retain a specific size wrench. A set screw is individually threaded in a hole intersecting and transverse to each wrench hole for tightening about a wrench in the wrench hole. A cap member is fixed to one end of the cylindrical member by a pair of flush mounted cap screws, with the holder fitted with a shaped recess open to the capped end of the cylindrical member for retention of small wrenches.
