Review: So handy - Decent quality and has variety of all the common fasteners in SAE and metric. It's so handy to have a bolt/ thread checker around. Fit seems decent for all fasteners I've tried this on. There are several styles, I prefer this style to throw in the toolbox and take out to projects and then take with me to inventory at the shop or to the hardware store.
Review: Works exactly as advertised! - Nifty little tool that does exactly what it's advertised to do! Now I'll know what size nut/bolt I need before I go to Home Depot! And I won't have to stand at HD's thread checker fumbling to see the right size of my nut/bolt! Again, nifty little tool to add to my colletction!

## Questions & Answers

**Q: Are the size markings embossed into each tool or just printed/etched onto the surface.**
A: Each thread checker is permanently identified by stamping. The zinc-plated inch series markings are then filled with red paint and the black oxide metric series with white paint. Identity markings include both the thread major diameter and thread pitch. If and when the filler paint wears out each size remains identifiable due to the stamping depth.

**Q: I'm looking for the most affordable thread checker, that has male and female threads for nuts & bolts. Also tells what drill size to use for each size**
A: The purpose of the thread checker is to identify existing threads.  There is no mention of drill size except that a 1/4"-20 bolt should fit a 1/4" hole and so on for each thread size.  If the intention is to thread something, drill size should be noted with the tap or dye.  Where these thread checkers really come in handy is for close SAE and Metric sizes.  I have several styles and love them all.  The thread checker on a flat plate like a drill gauge is the cheapest but it is good if it will fill your needs but the sizes are restricted.  The others cost more but are worth it.

**Q: what sizes  in inch identified**
A: Looks like someone else has answered your size question.

**Q: This looks like i can check a threaded hole for bolt size.  if i have a bolt i don't know the size of, will this work?**
A: Yes, this works for bolt thread identification. Each thread size checker has both male and female threads.

### ⭐⭐⭐⭐⭐ It's good.
*by M***E on April 12, 2021*

A long time ago I went to a website that sells hardware and ordered one of every size but and bolt they had. But it was only 19 sizes. This has 26. Anyways I tested them all and they were all smooth both inside and out. Pretty nice. Also, the sizes are indeed stamped in and filled in with paint. They'll never wear off. If you dropped them in acetone or something and the paint dissolved you could rub more paint over it and wipe away the excess with a rag and isopropyl alcohol. It's true, trying to thread one into a hole really sucks because they're all on a steel cable. The cable isn't the most flexible thing and the weight makes it worse. You can't feel what you're doing like that. I tried putting them on a string and that did help a lot because you could isolate one and let the string wrap around the bolt as you turn it. But not good enough for me. I knew when I bought these that I wanted to make a case for them and I did. I won't go into the details but if you're handy that's the way to go. Best part, I had 7 sizes from my first set that this set didn't have. 3 sizes smaller in both inch and metric, and one other inch 12-24. So now I have the ultimate bolt collection. I used thick foam in my case, drilled holes surprisingly easy and they all fit nice and snug. But you could also use magnets. 30 bucks is a lot of money, but I think it might actually be more to buy all this hardware individually at home depot or lowes. And to have the male and female on one piece with the size stamped in, yeah I think it's worth it. Very cool thank you.
