Abstract
A hand tool that can measure standard or metric hardware fasteners. By opening the tool and closing it on the nut or fastener, it will show the correct size of the fastener on a two sided graduated scale, one side for standard sizes and the other for metric, which is intergraded into the tool. The tool has a locking mechanism that can insure accurate measurement after the tool is removed from the fastener. The tool is compact to be able to reach hard to reach work areas.
