A fastener (10) includes an elongated shaft (14) having a first end (16), a second end (18), and a shaft body (20), a head portion (22), and a threaded portion (42). At least one inner feed channel (70) extends through the head portion and the shaft body and terminates proximal to the threaded portion. The fastener has a plurality of flutes (80) formed along and circumferentially spaced around an outer surface of the shaft body and an outer surface of the head portion. Each flute has a first end and extends from a first location proximal to the threaded portion, along the outer surface of the shaft body, and radially outward along the outer surface of the head portion. The fastener further has one or more lateral feed channels (90) formed laterally through the shaft body and connecting the inner feed channel to at least two opposing flutes on the outer surface of the shaft body.
