Info on both sides, and high quality plastic
My very fist review after years. Lazy! ⭐️⭐️⭐️⭐️⭐️ stars with a caveat - For the cost and overall function, this is great. I don't think you will find anything better. I have several screw and nut thread gauges, but these are in a large case, and not convenient to use for checking a couple of bolts/screws for daily needs. These smaller gauges like the BCP are perfect. I would have gladly paid more for a thicker unit, so there are a couple more threads. I also wish there was a measuring section for the length of bolts. It comes with information on both sides: One side includes ANSI and metric size and thread information (also drill), and the other side has tap. Includes both N.C and N.F. for ANSI - excellent! Easy to read and high quality platic. I have printed many different gauges, but they all pale in comparison. For $10, its one of my favorite tools.

Very accurate thread sizer.
It may be plastic, but it has good threads and accurate screw sizes, it is sturdy and easy to read. Definitely worth the price.

Works as intended but I really wished this was not plastic
I was looking tirelessly for specific tiny laptop screw online wasted 4hrs got no where...i cannot believe i could of saved hours guessing screw size and threading type, this really works and takes the guess work out. It would be a really nice tool if its made of some sort of aluminum or stainless steel, only time will tell.

Great Gauge
I was looking for inexpensive gauge for small metric bolts. I was leary about this one but now that I have it, it is great. I is plastic but it does have threads. As long as you are careful with it, it should last a long time. I'm very happy with it because it measures down to very small bolts. Worth the price, for sure.

Great to have
I know some peeps complained that it's plastic, yet, it's a very thick and sturdy plastic. Much thicker than I expected per other reviews

Works as advertised.
Works fine, just wish it had more thread sizes. It only has two thread pitch counts per standard size and one for each metric. Have to be a little careful that you do t cross thread or force a different thread pitch into the plastic guage. It would be very easy to strip out the threads.

Thread gauge tester, why guess when you can verify?
Handy thread gauge to verify size & thread count of Basic nuts & bolts.

J'ai differentes jauges de filetage, mais celle-ci est particulièrement utile par son principe et sans légèreté. En un clin d'œil ont peut vérifier diamètre et pas. Seule contrainte : elle est en plastique, donc il faut en tenir compte et ne pas forcer si la tige filetée n'entre pas de façon fluide.

Well made, has all internal threads. I have more metric hardware coming from China , so it is good to have

It could do with been a little thicker. However it’s a great product. I deal with both metric and imperial threads it’s a very easy check
