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

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.

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

I like this thing. It probably won't stop a meathead from forcing a metric screw into a standard hole (or vice-versa), since it's mere plastic; but it's helpful for getting a replacement screw without leaving the house.

Well machined, accurate and nicely marked.

Works great just what I was looking for thanks for this great product

Great tool; compact and accurate.

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.

Item is hard durable plastic. it has required holes for drill / tap sizes inch and metric. 1/8"thick.
