e90 wheel bolt sizes

alexwhittemore · 02-14-2013, 04:54 PM

I tried to get my wheels off last weekend only to find out the bolts were on so tight a friend's lug wrench wouldn't cut it. I went to my local hackerspace, where an impact wrench got nowhere. A 15" breaker bar and a shitload of upper body workout got most of the bolts off (which I then torqued to PROPER 88 ft-lbs), but one was on so tight it managed to split open the craftsman socket I was using (no impact sockets on hand, unfortunately), which had the side effect of totally rounding off one bolt head.

Anyway, I'm going to have to get some bolt extractors and a bar of my own this weekend, but that's not my question now. I need to get a replacement for the rounded bolt to put in when I actually get the current one out, so I'm looking at getting these:

(I'm not looking to spend a lot of money, so I'm just trying to match the current bolts, though if someone had suggestions for a set of 20 red studs/nuts or bolts in the $50 range, I'd be open to suggestions, though I don't think that's going to happen.)

Anyway, looking at those dimensions, they've got a 28mm shank and 54mm overall length, but measuring one of my current bolts, it's around 48mm overall and 25mm shank.

Is that close enough on a stock wheel that I won't hit anything internally when it's tightened down? It's not like I'm trying to put in a 45mm bolt, but then I also don't want to spend $20 only to mess up my hub or something.

Bump? EDIT: Finally found all the info I needed. Proper size is 25mm shank, 48mm overall, 17mm socket, 12x1.5mm shaft/pitch. BMW p/n 36136781150

Searched on ebay and got a 4 pack for $10.
