A plate-like device has six recesses in its top surface for holding in face up relation a set of six commonly used micrometers of from 0-25.4 mm (0-1") through 127.0-152.4 mm (5-6"). The width and length dimensions of the holder are approximately 187.325 mm (7-3/8") by 625.476 mm (24-5/8"), respectively, and the recesses are specifically arranged to be contained in an area of this size as well as being arranged in continuously ascending order from one end to the other. The particular dimensions of the device allow it to be inserted in and removed from a conventional tool box drawer in a snug fit. It is rigid so as to be self-standing and supporting when out of a tool box drawer and has finger notches for manual handling and removal and a side edge taper and bottom edge rounding for efficient insertion and removal relative to a drawer. The top surface of the device also has auxiliary recesses for holding calibrating standards and one or more adjusting wrenches.
