I went ahead and dropped the oil pan on my 540i to tighten the oil pump bolts. all were loose, some were in the pan and some were missing. I knew that there was no official part number for the 11 M6 bolts that clamp the pieces together. But after some investigative work at my local dealer, I have found a number for those bolts. dimensional and grade wise they are identical. grade 8.8 and made by the same company as the original. They look exactly the same too. Washer and all. Here is the number and the description. 07-11-9-903-854. Hex Bolt with washer M6x35-U1-ZNS3. Just thought I would let you guys know.
