Thread Checkers

Thread Checkers

The Clear Card Thread Checker is a clear transparent card with the standard thread pitches imprinted on it. It is very easy to line the printed thread marks with the actual threads you are wanting to identify. The marks run off the left edge so it is easy to measure on installed nuts with only a few threads showing. There is one card for Inches and one card for Metric. It comes with a protective layer that you can choose to remove. Also comes with protective sleeves to store them in. Handy pocket tool. It fits in your wallet where the credit cards go so it is always with you.
