I'm never removed one in that location. But once when I was beating out a stuck battery I dinged the tail cap lip. It was flared outward a bit, so it wasn't a true dent. It didn't damage the threads so I put the tail cap back on and lightly tapped the raised area down then ground it down with a dremel. The anodizing was lost anyway so it didn't bother me. It's a working light, not shelf anyway.
