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

This is exactly what I needed. A good gauge that is cheap and can quickly tell you what kind of screw you’re working with. I work with small screws and this thing fits the bill.

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 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.

Very helpful tool

It covers about any bolt smaller than a finger. It is plastic, so with lots of use I expe ct wear, but… It is a really well thought out tool, which is a high bar for a plastic sheet full of threaded holes. They went to the effort to print the markings on both side but then when the extra bit to organize the printing differently on the two sides so depending on how you think about sizing there is a side for you. One side has the diameter next to the hole and and the drill sizes in extra columns. The other side has the thread pitch next to the hole and the diameters in extra columns. So one side is your “how do I drill and tap a hole for this bolt I’m holding” and the other side is the “what kind of nut do I buy for this bolt I’m holding”. Well executed product, would buy the designer a drink.

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 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.

Perfect for determining the size of a bolt. Good value

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

Útil, con calidad.

Just very helpful
