Thread Detective Thread Identifier Set - SAE / Metric - Small Size

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 Thread Detectives® are 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.

Our Small Size Thread Identifier is available in Inch Only and Metric Only.

The combination unit contains both Metric and Inch nut and bolt sizes as stated below.
