Geeves, you say the bolts bent, I feel that if these bolts where a higher tensile strength they might have broke. I would much rather have a stretched/bent bolt and my hook still attached than the hook go flying because the bolt was too hard and broke.
As you also said, its because of all the different forces we put in all the different directions that you need a bolt with a bit of "give" in them.
Demonic,
If you are using grade 8.8 for the hook, then use either the eqivalent or the next grade up (10.4?) to hold the mount onto the chassis.
You are on the right track. You absolutely don't want a hook to break, thats why the right hooks bend rather than break. If anything is to break, you want it to be the lightest/softest item, as it will have the least amount of energy and hence can't do as much damage, ie snatch strap, winch rope with a dampener. You should always try to have the least amount if items in a recovery as possible - ie have hooks so you can hook the snatch strap straight onto the vehicles, if possible hook a winch hook straight onto the vechile if the hooks are big enough.
Oh how i miss my mu, the lux is just not the same
