A hand held measuring device for measuring the size of small objects such as nuts, bolts, and the like. The device includes both an English measuring scale and a Metric measuring scale and may be used to gauge the size of either a Metric or an English standard bolt. The device employs two pivotally attached plate-like elements, each plate-like element having a pincer element. Each pincer element has a contact point. The contact points of each pincer element cooperate to define the reference points for measurement. Further, the device includes a Metric and an English graduated scale and an indicating mechanism associated with each graduated scale. An object is measured by adjusting the distance between the contact points until the distance mirrors the overall dimension of the object. The graduated scale and corresponding indicating mechanism cooperate with the contact points to define the dimension of the object.
