Multipierce Reel-Feed ® Head BASE NUT PLUNGER PROXIMITY PROBE NOSE OIL FEED PAWL UPPER DIE SHOE OPERATION Strip Pierce Nuts are fed through a Reel-Feed adaptor connected to the head assembly. The nuts are fed automatically into ready position. The press, when lowered, forces the plunger to drive the nut into the part, supported by a die button. The die button forms the part material into and around the Pierce Nut undercuts and/or clinches the nut corners, securing the nut in position.
