A tool for forming a friction stir weld joint in a workpiece is provided. According to one embodiment, the tool includes a rotatable pin having first and second ends and defining a stirring portion therebetween structured to frictionally engage the workpiece so as to at least partially form the friction stir weld joint.

The tool can also include a second shoulder opposing the first shoulder such that the pin extends therebetween.
