This part is listed by BMW as BMW part number 11121738608 (11 12 1 738 608) and is described as the securing nut with an M6 stud to secure the valve cover to the cylinder head on M50, M52, M52TU, M54, S50, and S52 engines. This is a similar cap nut as used on the perimeter of the valve cover but this includes a small stud on the top. These engines use either 2 or 3 depending on the model.

Looking for just the sealing grommet? The grommet is the same as the outer seal and you can buy part #11121437395 as the replacement (see link below).

This is a Genuine BMW cap nut with stud with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
