My only gripe is that I would prefer the internal tolerance to be tighter against a 4-40 threaded rod which is very likely what the buyer would be using this for.
When using these in conjunction with the TCSS fins, they don't line up exactly in line with each other as they're stacked Washer - Fin - Washer - Fin, etc.
Still a good product though, just would prefer more exact tolerance.
