Hello, I am trying to clear out the for sale items, one shelf at a time, and I came across this set. Frederick Tool & Engineering Corp., Electronics Manufacturers. "Red E Nut" Nut Starters , for hex nuts ,sizes 2,4, 6,8, & 10. These are loaded by compressing the spring into the knurled cap, hex nuts are then placed on the guide pin. The handle is re-attached to the barrel, and when spring releases the hex nuts are forced against the plastic tip. Start the hex nut on the bolt, or stud, and tilt the barrel to release!!! Quite a contraption!!!!Regards, Lou
