Maybe try putting in a grade 8 bolt with either a double lock nut or nyloc nut with a washer on the lift pin before the bolt. I have lost a few bush hogging and broken some with the box blade but only after bending the lift pin.
Look for the cause of failure rather than constant pin replacement unless you were putting them in wrong which I doubt unless you are flipping the bail all the way over after installing.
