HexSizer Clear Card Thread Checkers are clear plastic cards with the variety of standard thread pitches imprinted on them. Simply align the profile with the thread pitch to confirm the threads of a fastener. One card shows the thread pitch profiles for Heavy Hex and the other shows the thread pitch profiles for SAE sizes. A very simple but effective idea as you can look right through and easily line them up.
