Finally got some time on the car today, so started drilling the floors, tried a rivnut on a spare piece of steel tube. I can fit them no problem but when I try to put a bolt in as soon as I get any tightness on it, the rivnut starts spinning. I've tried using the tool again to try getting it tighter even to the point of stripping the thread with the tool. I'm drilling the hole for the rivnut just big enough so I need to give it a little tap in. Any advice would be good as I'm obviously doing something wrong....
