FWIW, I've been replacing some worn out rubber bits here and there recently, and ran into the same issues you had.

Also West Marine carries them - they are used a lot on fiberglas boats to secure fittings...

Then I used some nylon thumb screws to hold the cowls down.

I ran a die over mine before adding antiseize and reinstalling without issue, but if the spare hardware I had on hand would have fit I would have replaced them.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Both of my rubber "cowl cover nuts" disintegrated. (They are the little rubber nuts that hold the screws for the two plastic covers on either side of the battery cover in the frunk.)
I bought replacements from the porsche dealer (P/N
999 500 092 00
). but they don't fit snugly in the hole. They are loose and will not stay in place when installing the screw.
I can see what looks like glue residue on the paint around the hole (see pic). Are these parts supposed to be glued in?
I just keep the screws anti-seized and press down gently on the cover to keep them from spinning until it begins to expand and holds itself.
The nut is cast into the sleeve if they are OEM
Thanks all for the quick replies!
@cboxell
your suggestion on technique was just the nudge I needed. I pushed down while installing the screws and it is good enough. I would've expected the rubber nut to have a firmer installation into the hole but, heck, these are just plastic covers that have been fine without screws for 2yrs so "good enough!"
Indeed the little nut was inside, cast into the rubber at the bottom, and not shown in my picture.
@SoCal911
in fact that is exactly the kit I bought after I saw you post about it previously. But those too "spun" in the little holes so I bought the porsche ones for $5/ea. I'm embarassed it didn't occur to me to push down on the cover to hold the nut in place while installing the screw and thankful to
@cboxell
for the tip. I just removed the Porsche one and tried the amazon one the same way and Voila! it was great. Your amazon pointer is right on the money. Reflecting all this here for the record.

FWIW, I've been replacing some worn out rubber bits here and there recently, and ran into the same issues you had. I think it's just not a particularly well-designed part (either that or we're both idiots...)
I just replaced these on mine. Bought Porsche ones after the Amazon ones I got sucked. The Porsche ones do have a nice thick top flange the others did not� the link above looks much better than what I had.
Two notes for using these:
First, the install torque is really, really low. Like two fingers on your 10mm socket low. They just need to fold the nut in the rubber up against the body of the car. Less is more, I presume that�s how the old ones blew up. Just take up slack and check you can�t pull the panel loose, and that should be just fine.
Second, the OE hardware in mine was all corroded/chowdered and I could barely thread them with the screw and nut in my hands let alone in the car. This is a failure mode for these nuts� if you force it you can strip the brass nut from inside the rubber bushing (especially cheapo Amazon ones). I ran a die over mine before adding antiseize and reinstalling without issue, but if the spare hardware I had on hand would have fit I would have replaced them. A stainless wingnut or **** would be slick here because the torque is so low, but they aren�t frequent service items either.
If I find I need more I�ll try the ones listed above. Obviously getting new screws AND nuts would be a boon if they are the right size.
I think these are called well nuts. Lowes and Home Depot usually carry them, too - not sure of sizes.
Also West Marine carries them - they are used a lot on fiberglas boats to secure fittings...
Yes, they are wellnuts, they are used a lot for motorcycle windshields and fairings as well. These are M5, and the SAI pump in the back uses some in M6.
the only issue with Lowes ones is they won�t be metric. Which may be ok-ish if you are getting a new screw, but I abhor mixing measurements/fasteners on a project let alone a car. If you or the next owner loses a screw or the wellnut blows up and they try to replace it they will rightfully curse you LOL.
My solution was to pick up some brass threaded inserts at my local ACE Hardware that fit snugly into the hole. Just for good measure I added a tiny bit of JB weld to make sure they wouldn�t move. Then I used some nylon thumb screws to hold the cowls down. Yeah, it�s not original and it�s not metric but it is simple, works perfectly and looks good.
I won't go so far as to say I'm not an idiot but I agree with you the size of the hole vs. the size of the well nut is not intuitive... Cheers! -Dennis
