Hex bolt with internal thread – BMW diagram

Callout 03 on BMW’s drawing “Generator, individual parts”. Open the drawing →

Hex bolt with internal thread — a genuine BMW part, number 12 31 8 574 809. You will find it under Electrical (Alternator with motor and mounting). It supersedes the older number 12 31 7 798 455, so a part carrying that number is the same part.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on 5 drawings, among them Generator, individual parts and Alternator 140/150A. It weighs about 100 g (0.2 lb).

Out of stock. Request it and we will notify you when it is in stock.
