Part number or thread pitch for nut behind volume knob?
Hey everyone, new member here and hoping to be one for awhile. I had an E39 wagon ages ago, finally picked one up as the new daily this weekend. One of the issues I noticed with my new purchase is that the volume knob wiggled and could be pushed in and out. I took out the radio and realized the knob switch was missing the nut that goes behind the knob, allowing the whole switch to move about. Does anyone have a part number for that, or willing to take theirs off to measure the thread pitch and nut height?
Yea except i’m missing the nut, hence why i’m posting -_- Luckily someone over on bimmerforums was able to send me a spare, turns out it’s a very weird nut. I think it’s a M7x1.25, my hardware store only had a M7x1.0 test stud and the nut could only get a quarter turn before binding. It’s about 6mm thick, and it fits an 11mm socket. Here’s some pics in case someone has to recreate it with washers or something:
