If your pinch bolts aren't staying tight you may not be torqueing them correctly. A paired set of pinch bolts needs to be 'snuck up on' to work right.
If you tighten one to the proper torque and then move to the next one and torque it, the first one will be loose.
The proper procedure is to snug them up slowly, first one, then the other, over and over until you get them both torqueed correctly. I use increments of about 5 pounds or so. When you are done the split gap should be nice and even, not wider at one end than the other.
The axle bolt should be lightly torqued (perhaps 10 ft pounds or so) so that the recessed head of the bolt is sure to be up against its shoulder in the fork lower. That big hex is there so that you can hold the head while doing this tightening. Then the head-side pinch bolts shoud be torqued so that the head can't possibly spin. The hex wrench shouldn't be needed anymore. Then torque up the axle nut and finish off with the nut-side pinch bolts.
The aforementioned didn't come from a manual, but there was a class at the School of Hard Knocks...
