ABSTRACT:
A heatstake for fastening a workpiece includes a base portion (12) having at least one shaft portion (22). A central passage (30) 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.
