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

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

Perfect gauge especially when you have a box full of different size screws to sort out

I had doubts if the M2.5x45 chinese knock off taps were actually that thread. They aren't This item whilst a little over produced should be good for pretty much all the small screws currently employed in everything from Glasses to Model Steam Locomotives. It is moulded from a half decent plastic which is it's only negative. It would be too easy to damage the threads if you use a damaged bolt that you wanted to check. It fits in my Tool box and being flat can stand to one side. I didn't expect much but it is better than the price indicates.

Handy tool for getting correct screw sizes

Expanded my knowledge on thread size. Well made, holes accurate, very clear markings. Both sides used / usable.

Just what I needed to help identify sizes of bolts, screws, etc. for drill bits. Great value for money. Easy to use.

Not very good value for price

I had bee looking for something like this for along time other gauges are multipurpose but a bit limited for screws. This is comprehensive

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

Útil, con calidad.

Just very helpful

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.
