Drill the old screw out of course, if you have to.
Obvious next steps:
- Re-tap with the same size and hope there's still enough metal to hold
- Re-tap with a larger size and just suffer with the weirdness of having an offsize screw there
But what about other options?
Has anyone ever tried a helicoil in a rack? I'm not sure if the few mm of steel on a rack is enough to use one. I've used helicoils to repair messed up threads on other hardware (things that go thump) but usually it is into a good sized chunk of metal.
Has anyone ever put JBWeld into the stripped hole and then drilled/tapped it afterward?
Edit: What about a clip with a captive nut on it, that just slips onto the rack and replaces the threads? Oh they're called 'clip nuts'
