A heatstake for fastening a workpiece includes a base portion ( 12 ) having at least one shaft portion ( 22 ). A central passage extends though the shaft portion from its leading end ( 28 ) to the base portion. A plurality of slots ( 22 ) are disposed about an outer surface ( 34 ) of the shaft portion ( 22 ). The plurality of slots ( 32 ) have a predefined angular separation. Preferably, the plurality of slots ( 32 ) disposed about the outer surface of the shaft portion form a heatstake having multiple fastening portions. The multiple fastening portions are adapted to form a geometric flower shape for increasing the fastening strength of a heatstake when staked.
