Door threshold hold down screws - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm sure most of you have had the problem where the hold down screws hog out the holes in the floor and no longer grip the sheet metal screws. So you end up using larger screws, but eventually they no longer grip the holes.

I'm considering drilling out the holes and installing rivet nuts for 10-24 machine screws. Have any of you done this? Any cons you can think of?

OK, after doing some research, my best bet looks like 10-24 machine screws with speed nuts like these:

I always thought sheet metal screws (non stainless ones, too) for that was an odd choice. I think rivnuts would be a great idea.
