Plain steel $13.58 for 20. Bet they are under a buck a piece shipped because McMaster's rates for shipping while not available at checkout have never been anything but amazingly low for me. Plus I bet if Mike orders them before about 7 today, he'll have them tomorrow since they have a location in Elmhurst, IL and their shipping is amazingly fast.
