An apparatus and supply strip is disclosed for inserting terminal pins into an apertured workpiece. The apparatus includes reciprocating feeding means for sequentially advancing a supply strip of integrally connected preformed terminal pins toward the workpiece; shearing means for severing the leading one of said pins from the remainder of the supply strip; and driving means for inserting the severed lead one of said pins into the workpiece. The feeding means comprises grasping means operable only when the feeding means is moving in a first direction toward the workpiece to grasp the supply strip at the juncture of adjacent integrally connected preformed terminal pins.
