The Thread Detective is a precise and easy-to-use thread identifier for both nuts and bolts, consisting 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 are available in Metric, English Standard, and a combo of Metric and English Standard. Thread sizes are permanently stamped onto each gauge. Our Thread Detectives are equipped with a 3-3/8 (85 mm) ruler for measuring stud lengths. The ruler can be printed with your company or customer's information for promotional use. 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.
