Wurth 10mm Electrical Body Nut + Washer

[BOTIGER1970]

Does anyone have or know where I can purchase the Wurth 10mm Electrical Body Nut + Washer
for installing my side marker lights for my 1970 280SL?  I need 8 of them.
Thanks,
Mark

What does it look like?

It is a nut with attached washer and a rubber washer that goes over washer. I checked with all vender catalogs including Authentic Classics and could not find the nut assembly.

It's really frustrating since I just checked myself, and it seems it is only available as a bundle with the whole side indicator.

I bought new side maker lights and they did not come with the nut assembly.

Hi,
Would plastic nuts be an alternative?

Try searching for "flange nut large flange (not serrated)" or "spring disc nut".

Rubber pads - probably to be fabricated...

I would think the plastic nuts are fine.
Because in the front wheel wells these nuts are subject to all weather conditions.
This will cause rust  and they will be gone.
It is simple to make the rubber behind the nuts.

Looks similar to the nuts used for attaching chrome trim to soft top hatch cover:  https://www.authenticclassics.com/Seal-Nut-for-Top-case-trim-230SL-250SL-280SL-REP-p/auth-007131.htm.

Not sure if these referenced above are the correct size you need. Even if they are, I tend to agree that using plastic nuts for that application makes better sense.

That is a common style nut. Has a captive washer that won't spin as the nut is tightened. https://belmetric.com/nuts/spinning-washer/ American cars used them in mass in the 60s and on.

Then it also has a rubber pad to seal. Just go buy a a 1/16" sheet EPDM rubber and make your own seal pad.

I have those same side markers. I am thinking the 10mm is the hex size, not the screw size. You'll have to measure the screw size to be sure.

Thanks all, for your responses.  I think the plastic nuts might be a good solution.  The Authentic Classics nut is not the right size.
