[DML] Re: Spinning screws in trunk


I had the same problem with some of the rivnuts in my car.
If they are not too loose (too wide a hole or damaged hole) in the 
fiberglass body part, there is a way to get them tightened again:

- Use a bolt of the same thread and of sufficient length (approx 1.5 
inch would do), a washer ring and a nut;
- Turn the nut on the bolt until is is close to the bolt head;
- Put the washer on the bolt;
- Turn the bold into the loose rivnut until it is against the collar 
of the rivnut;
- Keep the bolt in place and turn the nut towards the rivnut;

N.B.: This should tighten the rivnut again. Prevent the rivnut from 
turning while screwing in the bolt by placing the head of a screw 
driver under the rivnut's head (edge).

the metric sizes.  If you are careful, you can probably just run a 
tap through them to clean the threads and use the existing nuts.  Be 
liberal with the anti-seize on re-assembly, and I second Joe's advice 
to replace them with phillips-head screws.

> Are you sure the rivnuts aren't spinning in the fiberglass? That is 
much more likely than all the screws being stripped. BTW, those 
screws are all posidrive. A regular phillips driver will "cam out" of 
them faster than you can say "cam out". (Ask me how I learned this!)
Unless you have a posidrive bit of the correct size, when you finally 
get this issue resolved I would consider using phillips head screws 
as replacements for the originals.

> Hey Group,A semi-local owner trailered a non-running DeLorean?to? 
my house for basic restoration i.e. get it running again and 
reliable.? Nothing I haven't already done on my own car.? However, on 
this car, nearly all of the screws that hold the brake cylinder 
access panel to the trunk floor are stripped and spinning in the 
rivnuts.? I can turn them with vice-grips but the rivnuts are frozen 
to the screws.? I suppose I will have to grind off the heads and 
drill out the rivnuts, but how does one replace the rivnuts?? Is 
there a special tool?? Haven't had to deal with this issue 
before.Thanks, Andy Lien[Non-text portions of this message have been
