tap and die question Answered

Never used a tap/die but I bought a set, and it got dropped on the floor... It's all jumbled up and the markings are difficult to see (sizes). Do the two mates for each size actually fit together? I tried (lightly) to fit taps/dies together but none fit. I want to fix a metal threaded bolt and nut that are messed up.

Never thread a tap and die together it will damage them.

no, the taps and dies should not thread through each other like a nut and bolt.

your best bet is to get a magnifying glass and read the measurements. otherwise, if you have a matching nut/bolt to the one(s) you're trying to fix, you can pass the taps through the nut and it should match, and then the bolt should match if passed through the die.
