Not to sound like a know-it-all but I'm pretty sure that won't work. Here is the reason. A head bolt is torqued to a certain value. That value stretches the bolt and retains the "grip" on the threads which is why it doesn't back out. Don't torque it enough and it will back out. If I ran full poundage on my bow it very well could work. But once I back it off a turn or two the stretch is gone and I don't "think" it would make any difference from what I have now.

What gets me is I am the only one with this situation and I don't understand why?
