tap and die do not fit together Answered

Hi...this is also posted in the "community" forum, sorry for the duplication. For the bolt/nuts I have that are cross threaded or damaged I bought a tap/die set. Then I dropped it on the floor and it's all jumbled up. And the sizes on the taps/dies are very small....hard to see. So I thought I'd match them up by fitting them together but none of them fit together (die/tap). I'm curious, shouldn't they fit together?

Yeah. I used to know why- back when I worked in machine shops.

The right cross section diagram would probably explain it better than words. haven't found that pic yet, though.

Nope, that is why they are marked with the sizes and thread pitch if other than standard.

If you bought an unmarked set you might want to return it.
