Cutting new threads into frame nuts?

[SuspectLJ]

I tried doing a search cause i have a feeling this question has been answered before but i couldn't find anything.
Not quite sure how i did it or if it was the previous owner but the two lower nuts that are welded in the frame for the front bumper are stripped. I'm trying to find the simplest solution and was wondering if anyone here has had any luck using a tap to cut new threads into them.

ideally I'd like to have all the bolts in the bumper for recovery reasons.
if anyone has a better idea I'm all ears.

The tap will work, generally. Next size larger will be 9/16" coarse or 14mm x 2.0 which are close enough diameter wise that you can pick either one.

When you start cutting new threads; ONLY turn the tap 2-3 turns CW and then turn CCW to clear the cut metal particles.
Turn the tap in another 2-3 turns past where you were previously and then turn CCW to clear the cut metal particles.
Continue this cycle until you have finished cutting the new threads.
This sequence will ensure you don't clog the cut threads with metal particles and ruin the freshly cut threads.

Would these work on a 2000 TJ or would it be different?

I retapped the one stripped nut on my front bumper to 9/16. Thinking about doing the rest when I pull it off next year to clean everything really well.

Neither. Those nutserts are for the belly skid. The OP's issue was with the front bumper nuts...

I wouldn't.

...and the reason for Blaine's comment.

Ahhh, got it. I'm having a similar issue with a rear bumper nut.

If you have a slip over bumper, those belly skid nutserts will prevent you from installing it after the nutsert goes in. The flange on those is almost 1/8" thick so you would need a poorly made bumper with a lot of top to bottom slop built into it.

Yeah, I was looking at that and was thinking that would be an issue.
