I finally got around to bolting the winch to the front of my M813. The winch was bolted to four pieces of angle which were carriage-bolted to some 2x6's for shipping.
What grade of hardware should I be using for the four (4) bolts on each side that attach the winch to the side-plates? I seem to recall reading that you should NOT use grade-8 hardware for attaching winches. I used the bolts that were in it - the markings on the heads made no sense to me. The heads were thicker than a standard gr5 or gr8 bolt. I cranked them on with a 1/2" impact gun and broke one off.
I used a grade-5 bolt to replace the one I broke. Is grade 5 OK? Were the bolts with the taller heads and odd markings military hardware? Should I replace them (I'm concerned I may have stressed them with the impact gun since I broke one of them off) Thanks.

A lot of the TMs have in there some place show about torque specs and show the head of the bolts and what the markings mean. LOOK!
