A self-piercing pin and method of installing same. The pin includes a body portion, a pierce ring, a flange, and a lock groove which is disposed between the pierce ring and the flange. An angled surface is provided between the pierce ring and the lock groove. A top side of the flange is generally flat so that the flange can be set flush to the workpiece, and to enhance the side load strength of the pin once the pin is installed. A bottom side of the flange is beveled, angled or flat, thereby minimizing the amount of workpiece material which becomes displaced during installation. Upon installation, the pierce ring shears the workpiece, and the material of workpiece flows to the lock groove portion of the pin, thereby forming a mechanical lock between the pin and the workpiece. A driver and a die are used to install the pin.
