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

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

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.

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.

Anyone with an extra old toolbox full of screws,bolts,nails... this thing is so useful!

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.

Handy thread gauge to verify size & thread count of Basic nuts & bolts.

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.

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.
