Hello All,
I recently acquired a set of cupped finish washers from Germany for the eight grille surround attachment screws.They have an M-B part number and packaging, but they do not look quite right.
I have always believed that when an oval head screw is pocketed down into a finish washer, the dome of the screw head should be flush with the cupped edge of the washer. After all these years of designing and building things - - - am I wrong about this ?
The photo of the screws I bought says it all. Not only is the screw head too big , but why is a zinc plated screw mated with a stainless steel washer ? Needless to say, his will never get past a Concours Judge inspection team. I should know - - Pete Lesler trained a group of us last summer.
On my car the drilled hole that accepts these screws is way over-sized now, the result of previous owners using #12 sheet metal screws instead of the proper #10's ( or should they be #8's ?). To get back to the way it should be, I am going to have to install a Tinnerman nut-plate or make something that will do the job.
In my nuts and bolts bins I have been able to find suitable replacements for the screws, see photo, so I am forging ahead.
Regards, Larry in CA

Larry,
I have just had the same problem with my grill and replaced the wrong screws from the body shop with what I think are the correct screws but had the enlarged holes problem. I used Joe A's method of using a piece of copper wire in the hole to start with the screw and it worked a treat and the screws gripped and the copper does not show.

Hi Larry,
not sure whether I am understanding your question. Did you buy the cup washers and the screws together or are the from different sources? If you bought the together then the seller made a mistake.
First, the screws should not be gray steel but chromed and should be oval not a pan head - but it is a bit difficult to see what their profile is. What is the p/n on the bag? The should be neither a #10 nor a #8 but a metric DIN screw!! The cup washers your photo do not look correct either.
Do you need the correct p/n for the cup washers and the screws?
This shows what the cup washers should look like: http://cgi.ebay.de/370502537270
and here are the matching screws: http://cgi.ebay.de/370502537322

Thanks for pointing that out. I bought the same set a year ago and never looked at them just threw them up on the shelf with the grille. Now I am looking for chrome DIN screws.

In case it may help, here is a photo of a Grill screw thaat was pronounced "correct" by long time judge of Pagodas.

I thought the screws were meant to be chrome plated. The screw looks like it is zinc plated?

I can safely say that mine are original and look like 280SL71 above.

John,
unless you're taking your car to a MBCA event where it will be judged by '' trained '' experts, what real difference does it make? Aside from knowing that you have a perfect, correct car, who's going to see it, or care for that matter?
I mean, it's not like we ( the web forum members ) have a dedicated car show or judged events, right?

That's a fair statement and someday maybe there will be a clublike judging that is fun and educational. Some folks want to be correct for their own enjoyment (bragging rights?) and I just offered mine as a high likelihood of being correct considering its history. They appear to be the same as what's used on my 190 SL.

So, are the screws chromed or Zinc plated?

Hi All
New Pagoda owner here. I have sheet metal screws in my grille and my cowl vent (duh! - who would do that?). I've replaced a few missing tinnerman nuts, etc. but here's my question -
On the top of the cowl vent, I have an empty hole. Is there some sort of fastener that goes in there? If so, what's it supposed to do?

Looks like chrome to me

Thanks Naj. Looks like I have some work to do.

Perfect John, you get a price. ;)
The p/n for the screw is 007983 003216. That means DIN 7983 and DBL (Daimler Benz Liefervorschrift=supply spec)) 8454 which specifies a lens head counter sunk screw, 3.9 x 13 mm, finish: chrome.
The p/n for the counter sunk washer is N900056 003507 - about $3/each from MB - ouch!
-
I recently replaced mine with parts from mercedes and have the ones like the red car above, both the countersunk washer and screw are chrome..
-
Im fairly sure the screws and CS washers should all be chromed. There is a kit below with the correct MB parts for reference.
