Thread Detective Nut & Bolt Size and Thread Pitch Identifier Gauge, Metric - Small Size Range 


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.

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.
