    STOP Guessing - Start Checking with the Thread Checker!

    Sick of spending time fumbling through boxes, jars, or drawers trying to figure out what size nut, bolt, or screw you need?
    Tired of the multiple trips to the hardware store and the wasted money on incorrect sizes?
    Don't you wish you had a tool that would quickly and easily determine BOTH thread pitch and diameter for the most common nuts, bolts, and screws?
    Your search is over...the tool that you've always wanted is finally here!

    The Original Thread Checker is an accurate and easy-to-use thread identifier for both nuts and bolts. Each individual gauge features a male threaded stud on one end and a female threaded hole on the other. The Thread Checker is especially well suited for distinguishing between similar inch and metric threads. Conveniently assembled onto a wire loop, it's the perfect portable solution!

    Each size has a bolt and nut thread checker on the same gauge. Thread sizes are permanently stamped onto each gauge. Unit comes with a wire cable with loop on each end for convenient hanging. The individual gauges rotate freely on the wire cable for fast verification.
