You're sorta right... both the 12mm bolt and nut use an 18mm socket. The 14mm bolt also takes an 18mm socket, but the 14mm nut needs a 21mm socket.

How likely is that bolt going to rust? Would a stainless bolt be better? Do they make a 9/16 12 Cap screw in stainless?
And about the the Rear IRS bolts from MM, I agree with one of the above statements that these should be a torx head. I have not bought MM's yet b/c I don't want to go through the hassles all of you have already with the allen head stripping. I've been looking for some torx head bolts but absolutely cannot find them! Most of what I find is small but I know they make larger ones...my trucks seats are bolted to the floor with T50 or T55 torx head! Just my $.02
If you buy a quality allen head socket you won't have that problem. I thought it was a bunch of crap myself until I found out first hand. And when I mean a "quality" allen head socket I'm talking about Snap-on, and yes it is that big of a difference.
The first set of bolts I had I stripped out trying to torque them to spec with a Craftsman 8mm allen socket. Jason at CSS told me that a Snap-on socket would work better and so I had a friend order one for me... was 18 bucks I believe. I can torque the MM button head bolts on the rear all day long at 76 ft/lbs. with that socket and it not think about stripping out the head of the bolt.
Craftsman 8mm socket measured out at .312, which is really 5/16". The Snap-on socket measures out at .315, which is what 8mm really is supposed to be.

I installed the 9/16" in the front. At first it would not fit. I took a round file and "lightly" went around the hole. I think it was just some slight burrs from the manufacturing process. The bolt slid in perfectly after that.
