Trying to chase threads with a new, sharp tap is a good way to oversize the female thread and create a sloppy fit
Totally agree. But, if you happen find yourself without a worn tap to fit your application, Snap-on, Lyle, Craftsman, and others offer kits like these.
They even include thread files which are handy for things like cleaning up the threads of the stubs of full floating axles, after some idiot has used a chisel to tighten the bearing nuts...
Best Regards....
