Thread Detective - Thread Identifier Metric Jumbo Sizes

The Thread Detective is a precise and easy-to-use thread identifier for both nuts and bolts that consists of gliding gauges conveniently assembled onto a wire lanyard. It is especially well suited for distinguishing between similar inch and metric threads. Our unique Thread Identifiers (aka thread checkers) are available in Metric, English Standard, and a combo of Metric and English Standard. For your convenience we provide extra-long wire rope for those hard to reach places, as well as loops on each end for convenient hanging.

Metric Thread Identifiers contain nut and bolt sizes of M14x1.5, M14x2.0, M16x1.5, M16x2.0, M20x1.5, M20x2.5, M24x2.0 and M24x3.0
