Here's a handy pliers used for beading. You can find these at hobby shops and in just about any fabric shop that has a crafting section. Hobby Lobby and Michaels also sells them. The jaw is designed to hold a bead while stringing them, but fits a 1/32 head perfectly and will also hold a 1/64 or 1/16 without marring the heads. The smaller inside pocket is for the 1/64 heads. I grab the head in these pliers and twist off the sprue with the fingers or a needle nose. I don't have any issues with loose heads using this tool.
