Ah, yes ROSCO, I've been a bit of a fool here...

Clearly they would have to or you would have to pull them out and replace
when you need to move a beam's position! And if they were tight enough to
resist any rotation you would never even be able to get them in!

I think the black pins are made from much softer plastic and this melts,
perhaps even at room temperature due to the inherent friction, welding them
into place. I would suggest this means that rotating them somehow would be
the best way of breaking the weld. I've never had any which required
drilling out!
