Inch Thread Identifiers contain nut and bolt sizes of 5/8-11, 5/8-18, ¾-10, ¾-16, 1-8, 1-12

The Jumbo 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 unique Thread Identifier (aka thread checker) is available in a combination of all Metric and Inch sizes. Our Thread Detective is 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.
