The Thread Detective Thread Identifier 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 Thread Detective® is equipped with a 3-3/8" (85 mm) ruler for measuring stud lengths. 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.
Inch Only and Metric Only Strands are available.
