The Lug Thread Detective® is the most useful and necessary tool in any mechanic's tool box, tire shop, automotive repair shop, and in every gearhead’s garage. The Thread Detective® is a precise, portable and easy-to-use thread identifier for nuts, bolts, tapped holes, mounted or affixed studs, including lug nuts and wheel bolts. Each individual steel identifier is permanently laser etched with the thread size and features an internal female threaded hole accompanied by a male threaded stud on the opposing end. The inch and metric identifers are simple to differentiate as the inch stand-offs are seperated by red impact resistant dividers and the metric with blue. The gliding identifiers are strung onto an extra-long cable for easy separation.
