Lug Nut Size

Quick question what size are our lug nuts?
And where I be able to buy new ones?

Just got some new wheels on and thinking about changing to different lugs.
Heres a crappy cellphone pix.

The shortest they have is 28mm, would that be too long? That's an additional 1.1cm longer than the stock size that Derspeed said.

You mean acorn seat or tapered 60 degree seat? Acorn seats are usually found on OEM wheels. Aftermarket wheels usually use the 60 degree seat. Not interchangeable, if you are going to swap wheels, you'll need the tapered seat most likely.

Speaking with one of my shops, they said that the 28mm length on the Kics bolts should be ok. I was running 25mm ones on my Work wheels. They are tapered, so you will need to run them with aftermarket wheels, they won't work with your stock wheels.

EDIT: Checked MB OEM parts online stated they use M14 27mm lug bolts.

Sorry for reviving an old thread,

but i just picked up a set of euromag em2's and im guessing i need new lug bolts?

IIRC the stock lug bolt length is 27mm?
So would 33mm length be sufficient? (but not too long?)

also should these be ball seat?

quick response would be appreciated, would like to get the new shoes put on today.

thanks

Almost all non MB wheels are conical seat, regarding length you should look for a bolt that is protruding about 12-15mm.s once the bolt is seated in the rim
