Self-locking hex nut — a genuine BMW part, number 31 32 1 139 422. You will find it under Suspension (Other Front Axle parts). It supersedes the older number 31 12 2 160 247, so a part carrying that number is the same part.

BMW draws it on 41 drawings, among them two Guide Support/Spring Pad/Attaching Parts drawings. It weighs about 20 g (under 0.1 lb).

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