The Metric Thread Checker is an accurate and easy-to-use
thread identifier for both nuts and bolts. Each individual gauge features a male threaded stud on one end and a female
threaded hole on the other. The Thread Checker is especially well suited for distinguishing between
similar inch and metric threads. Conveniently assembled onto a wire
loop, it's the perfect portable solution! Hang it on your shop wall or store it in your tool box for safe keeping.
