Inner hex bolt — a genuine BMW part, number 34 43 6 783 644. You will find it under Brakes (Other Brakes parts). It supersedes the older number 34 43 6 778 501, so a part carrying that number is the same part.
Fits E46 320i, 323i, 325i and 328i (1999–2006) with the M52, M54 or M56 engines.
BMW draws it on 3 drawings, among them two Control unit box drawings. BMW's catalog calls for four of these at each place it is fitted. It weighs about 10 g (under 0.1 lb).
