radiator bolts- 230 SL

[McBenz]

I would like to replace the (6) screws that hold the radiator in my 230 SL , anyone out there know the type of bolts they are? Or the part number for them? Any help would be greatly appreciated, thx.

Early 230SL have a hex.head screw M6 x 12mm plus a spring steel cup washer p/n 0009900148 and later ones a combined hex.head screw with integrated cup washer p/n 1105000085. I don't know the date of the switchover and I believe the 110 p/n is nla.
The regular DIN 933 hex. head screws are readily available and the spring steel cup washers are available from Grainger: https://www.grainger.com/product/SPEC-Disc-Spring-22RG43. That is what I used recently. See my photo here: https://www.sl113.org/forums/index.php?topic=30649.msg226995#msg226995
