Stripped sill holes
Finally got my carpet installed and am starting to reinstall trim. When I started to reinstall the door sill plates, I found out all the screw holes were stripped out. What's the best way to fix this? Fill them with something like jb weld and retap them? Thanks for the help.

I'll take some flack for this but what I did was use some of the yellow plastic mollies that you usually stick into drywall. Stuck them in the hole, ran the screws in, tight ever since. Guess I'm Bubba!

If you can't find a little larger screw, metric maybe, what about trying one of those drywall anchors? Or put a small piece of (copper/solder) wire in the hole and use the screw that goes in there?

Yep, cut to length, insert and you're good to go. I used thes on the numerous stripped holes in the dash pieces as well. The hardware store also sells the drywall anchors in kits, that come in various sizes, besides yellow.

I used stainless steel rivnuts and epoxy glued them into the stripped out holes rather than install them with the tool. Used stainless steel cap screws with a bevelled head to hold the trim in place. Looks good, not NCRS but better than the rust prone std screws (I hate self tapping screws on a car so avoid using them wherever I can). Factory liked them they were cheap:-)

FWIW, I've found success when trying to put a screw into a soft piece of trim by first putting a small piece of heat shrink tubing over the threads of the screw, then heat it to shrink into place. My logic was that I'm only adding to the soft trim so it should not be a problem.
I'm not sure how well this would work when going into something hard like the sills, but I would definitely try this method before drilling into the car.
Hope this helps...

The plastic drywall screw inserts will work. I prefer to fill the hole with JB Weld stick-type [putty] epoxy; let harden; drill for screw size; tighten snugly...but not 'tight'. This works well with interior screws and parts.

Set the Mig on lowest setting....weld holes closed/grind smooth/re-drill to proper size.....
OR
Install Rivet-nuts (crimp them tightly to keep them from loosening---use matching machine thread screws to avoid stripping in future)
OR
Use the Blue ones that M.W. uses!

May not be high tech but stick a piece of .032 safety wire shaped like an "L' in to the hole. The "L" shape will keep the wire from falling into the oversized hole. The screw will tighten up just fine. You can go up a size if you need too. Work's fine for reamed out interior panel holes too.
