Help Identifying Hardware Found in Belly Pan

[bimmerfan08]

While performing work on my M3 this past weekend, I dropped the belly pan and found a few pieces of hardware that need further identification. Thanks to anyone who can advise.


For reference:

1. I noticed the hex bolt head sheared off the front oil pan corner bolt somehow (will have to extract the threads and replace)
2. The threaded stud appears to be the stud bolt used for the oil dipstick (see diagram below), but I haven't confirmed
3. The larger bolt is an 8.8 grade bolt

Update. Did some more investigating and looking around under the car today.

Larger bolt (M8x20) secures the power steering bracket to the engine block. The long stud appears to be on the beauty cover cap studs. Dipstick stud was secure with the nut still in place.
