## Questions & Answers

**Q: Do the holes have threads so you can screw in a bolt?**
A: Yes. The gauge is a thin piece of plastic and each hole is threaded. There is, of course, a limited number of threads because the plastic is thin. I believe it should be used gently to avoid damaging plastic threads. I believe it will be useful for identifying whether a screw has one standard thread (such as 1/4-NC20) or another standard thread (such as 1/4-NF28), but I don't think it can be used to finely test accuracy of threads cut on a lathe. I have not had an occasion to use it yet.

**Q: what is the thickness of this gauge?**
A: My micrometer says it's about a quarter inch. The only caveat is it is a polymer gauge, good news is that means it's durable and can flex around truly messed up screws and bolts; the bad news is it's not super precise because it's not stainless or Ti. For example it might be hard to discern a 24 vs. 28 pitch thread, but in my experience in the machine shop it determines the right threading well especially when you are trying to match a screw that's broken, old or damaged.

**Q: will this guage work for very small computer screws ?**
A: Yes! The guage goes down to M1.4 which is much smaller than any fastener that your going to find in any computer.  The guage also has inch sizes down to #0 (.060 inch).

**Q: Why do they show two different kinds of cards in the picture? One says "pitch" at the top right, and the other says "drill". Which one do we get?**
A: The pitch is for metric screws.

### ⭐⭐⭐⭐⭐ Brilliant

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

### ⭐⭐⭐⭐ Ideal from the land of the bright idea...
*by S***N on 4 July 2025*

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.
