Abstract
A self-drilling anchor assembly including a drill bit and an anchor positioned over and attached to the drill bit. In various embodiments, the drill bit includes a shank, a drill head integrally connected to one end of the shank, and a threaded tail integrally connected to an opposite end of the shank. The tail includes a mechanical engaging structure that is engageable by a tool to rotate the drill bit, and a helical thread formation to facilitate attachment of a securing device such as nut and washer to the tail of the drill bit. The anchor includes an elongated generally tubular body including an inner surface defining a longitudinally extending inner channel, and a head integrally connected to and extending from a first end of the body. The drill bit is configured to remain in the anchor and in the substrate after installation of the anchor assembly in the substrate.
