I know the word Radial is becoming commonly used for all Ball Screw pins just like Asprin is for all kinds of headache medicines. But remember any other radius threaded ball screw joint pins are not supposed to be called Radial pins. The brand names Radial and Uni-Loc are trademarked and the guy who owns the trade marks is a little fiesty about people using it for pins that did not come from him, whether they have the same thread pitch or not.
