What kind of screw is this??

(Edited: ......I think I just now found out what kind of bolts these are.... These are rubber stud bolts. My mechanic told me they're threaded on the underside, so you screw them into the frame of the car and the rubber with the bolt is on the topside. He said the flathead bolt is glued to the rubber. He said Superglue is enough to hold the bolt to the rubber).




I'm trying to put the monowiper back on my 1991 300d W124.

There are 2 rubber bolt posts on the left; an upper and lower one. You slide the slotted area of the monowiper over the bolt posts and put the nuts on the posts to tighten them down. The 2nd photo that I got from a YouTube video shows what it is supposed to look like with a hex shaped bolt with hex shaped rubber backing there.

Back to the 1st photo, my lower bolt is there and it has a gold color nut on. But the upper bolt is gone from the rubber. Maybe when I took the monowiper out, that bolt got hit and came off. I thought the bolts came up THROUGH the middle of the rubber but apparently not. Without the bolt being there, then I guess they're simply glued onto the rubber.

It seems weird that I would be tightening a monowiper down to a bolt that is held down only by some glue onto the rubber??? Can this be for real??

How or where can I get a replacement bolt, or adhere a bolt onto the existing hex black rubber that's still there under the monowiper? Not sure what type of glue they would have used to hold a bolt in place on rubber.

Thanks.
