Review on Nut Bolt Thread Checker Metric by Chris Quinto

This metric thread tester is simply the best I have ever seen! A little pricey but superb craftsmanship and finish. I bought both inch and metric sets of 21. They are supplied on stranded wire with a white bead separator. Each thread tester has an individual size marking. You can hang the wire rope on the wall with thread testers, store it in a tool box, or take it with you to the field. The company also makes a wall-mounted thread tester if that's your preference. These thread testers are made in the USA by SW Manufacturing, Bensenville, Illinois. The company does not sell directly to customers. I recommend this product.
