Has anyone else experienced this?
Mark,
It could be that you are tightening the set screw way too far. I've used the locking pin backs for disney pins on hats. The post will get pretty rough when I over tighten the set screw. Remember you don't have to tighten it down until the screw doesn't move anymore.

I tighten them down until the pin is pressed against the opposite wall of the barrel, and then give another 1/2 to 3/4 turn and I've never had a problem.

Also I'm not sure where you bought you locking pin backs, but the ones I use for Disney pins, the set screw is rounded on the bottom, so if anything I leave a divit in the pin.
