The Thread Detective™ is a precise and easy-to-use thread identifier for both nuts and bolts, consisting of thread checkers conveniently assembled onto a wire lanyard. It is especially well suited for distinguishing between similar inch and metric threads.
For Easy Checking of Internal and
External Threads
Our unique Thread Detectives™ are available as a
combination of Metric and Inch sizes:
The Combo Thread
Detective™ has the following checking sizes:
Thread sizes are
permanently marked onto each piece and are coated
with a clear PVC cover to prevent the markings being
erased. Our Thread
Detectives™ are equipped with an 85mm 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.
