I'd like to make a comment here. As we know all bolts/studs, what have you, have a certain torque spec that yields the best holding power and strength.
Just making sure something is "tight" is not always enough. If when you go to check that it's tight, and you give it a small turn to just make sure, you are adding that much more stretch to the fastener. Over time this will be just as bad as running a fastener loose.
Not saying anyone should carry a torque wrench with them on the slope. Just an idea as to why one's bolt might fail after making sure it was "tight".
