Abstract: Pile connection methods and devices are disclosed. In some examples, a pile connection device includes a plug including a head, a body extending from a distal end of the head, a first bolt aperture extending through the head and the body and configured to receive a bolt, and pins extending from a distal end of the body. The pile connection device further includes a nut including pin apertures each configured to receive one of the pins, projections extending from a circumference of a proximal end of the nut, and a second bolt aperture that is threaded and configured to align with the first bolt aperture when the pins are received by the pin apertures. The second bolt aperture is configured to receive a threaded distal portion of the bolt to thereby draw the nut toward the plug and retain the pile connection device within apertures in the connected piles.
