A threaded termination (10) for helical piles (20) has an elongated shaft (12) and a substantially square cross-section. A series of uniformly-spaced notches (14) on the corners of the termination shaft (12) are aligned to form partial threads around the termination shaft (12). A coupler (16) on an end of the termination shaft (12) has a socket (17) with a substantially square cross-section. In use, a helical pile (20) is initially screwed into the ground. The coupler (16) of the termination (10) is then attached to the upper end of the helical pile (20) with the shafts of the termination (10) and helical pile (20) axially aligned. The assembly can then be screwed further into the ground by applying torque to the termination (10). The upper portion (18) of the shaft (12) of the termination (10) can be cut off, as need, and a load transfer device (30) is then threaded onto the upper end of the shaft (12) of the termination (10).
