Please post a picture of the 'bent' pin and the receiver holes.
Thinking semantics here. I picture in my mind a 'bent' pin as a nail
that was miss hit and bends.
Wondering you are referring to a pin shank misshapen-ed from the shearing
between the receiver pin box, the insert and shank. Looks like it was
almost cut by scissors
As far as I know, receiver pin boxes are dead soft, or not hardened
So the pin would either be the same or harder (think harder) and the
hole in the receiver pin box would be buggered up (oval'ed)
The picture would tell if a large impact event happened or a series
of small banging's over time
