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

A tool that will cut down my trips to the hardware store by a large percentage. Finally I have a device that takes the guesswork out of knowing what screw size I need to buy.

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.

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.

It's a good product

Works perfect. Has about every thread count and size that exists

Great item, use it faily

Works well for what it is, but it needs directions to tell you what everything it does. It is two sided and if you don't know everything there is to know about screws, nuts, and bolts, it is hard to use. I purchased this item to separate screws that were in a big pile, that I had received from a friend.

Well machined, accurate and nicely marked.
