I've been watching the Brook Reams YouTube video on changing oil and he discusses replacing the standard bolts with allen head bolts. I've been searching the parts microfiche (Bob's BMW) and I can't even find a part number for the standard bolt. Any idea where to find the allen head bolts, or the p/n for the standard bolt?

You can buy the M6 SHCS fastener at any good hardware store in black or stainless. Both will be Grade 5 or higher. Just remove one stock hex bolt and match the shank length when you get to the store.

Yes, using this method you'll pay 59 cents for a 12 cent fastener, but you're only buying 3 (and maybe a spare). 

[It's important to state that the change in fasteners does not mean an increase in fastener torque. More torque does not prevent oil leaks... replacing the o-ring (in the case of oil cooler models o-rings) prevents leaks.]

IMHO, this "advantage" really only works if you also buy the 5mm hex socket to use on the end of a "speed handle". In this way you can access the fastener straight on, rather than from the side (as you presently do with a spanner).

Hope this helps.
