Screw Thread Gauge | Metric and SAE | Recommends Drill Bit & Tap Size (BCP675)

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.

This is a very useful and handy tool for your projects. It’s easy to carry and can be important to determine the proper size to use so the. Fit is correct and solid. I highly recommend this

could be a bit thicker, otherwise perfect for finding the right screw.

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

I like this item because it helps identify both Inch and Metric screws with one screw checker. The metal ones I have are either/or - Inch/metric. It is unlikely that the threads will wear out on the metal guides but I'm not convinced the plastic one will be as sturdy. I like that both types are on one tool. I'm sure it will work well with new screws - not sure how it will work with worn or rusty screws. I also like that it gives you an idea about which drill bit to use to drill a hole for the screw. I have a couple of other plastic guides which are more robust but I think this one will work OK if I take my time and be careful with it. For $10 it does the same thing the $50 units do.

Very Handy

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.

Very good!!

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.

Este calibre de roscas no debería faltar en ningún Taller

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

Útil, con calidad.
