I need a piece of 5/8" rod for a center pin for a boat roller about 12"
long. Will there be any difference in cold versus hot rolled for this
app? Very very little roller movement over the period of time. Think I
may just tack a washer on each end, and keep it simple. Or should I drill
and put a cotter key, at least on one end so it can be removable if
needed?

If its just a bump roller and your boat rests on bunks I wouldn't worry
about it. Just get it on there.
