Unfortunately both David and Pat are referring to "real" 6-pin drive wheels where the pin is only 1/2" diameter (and ours is on a 3/8" stud). Yes. That design is torqued to only 35 lbft.
But what the rest of us are talking about is the 5-pin system that uses an adapter that's bolted on with special nuts that do double duty also as the drive pins.
Small picture from the Vintage Wheel site, but maybe you can get the idea.
