Abstract

A measuring device allows simultaneous determination of the length and diameter of elongated fasteners such as bolts, screws and the like. The device has a body member with a plurality of variously-sized holes extending from a gauge surface. The body member is preferably marked to indicate the hole size. A panel member is attached to or integral with the body and defines a plane extending parallel to the hole axes and spaced therefrom. The panel member carries indicia which indicate length from the gauge surface. Insertion of a bolt into the smallest hole which will accept it identifies the bolt diameter while comparing its end with the panel member indicia indicates its length.
