A fastener includes a first end, an elongate body, and a second end. The first end includes a cylinder having an entry aperture at a terminus, a wall, and an inner lumen aligned with a longitudinal axis of the cylinder. The lumen terminates at the entry aperture. The elongate body is aligned coaxially with the longitudinal axis and contiguous with the cylinder. The second end includes an insertion body aligned coaxially with the elongate body and contiguous with the elongate body. The entry aperture and the lumen are configured to receive the second end. The second end is aligned to penetrate the entry aperture and thereafter enter the lumen.
