Abstract
A helical pile coupler, assembly, and method of assembly. The assembly comprises a first pile segment having first end with a coupler attached thereto. The coupler has two or more coupler aperture pairs and the alignment of at least one of the coupler aperture pairs is radially offset from the alignment of at least one other coupler aperture pair. A second pile segment is receivable in the coupler and the second pile segment has two or more pile aperture pairs that can be aligned with at least two of the two or more coupler aperture pairs, including the at least one radially offset coupler aperture pair. Fasteners are extended through the aligned aperture pairs to secure the second pile segment to the coupler. The fasteners are configured to protrude minimally from the outer surface of the coupler.
