摘要： A fastener including a body having a threaded portion and an opposing, tapered portion, where the tapered portion includes an outwardly angled surface, and a sleeve movably connected to the body. The sleeve includes a plurality of fingers at least partially separated from each other, where each of the fingers includes at least two, axially spaced gripping members protruding from the body. When the fastener is inserted in a borehole formed in a substrate and a fastening member is threaded onto the threaded portion and tightened, the sleeve progressively moves along the angled surface causing the fingers to move outwardly and at least one of the gripping members to engage an inner surface of the substrate forming the borehole to secure the fastener in the borehole.

摘要： Various embodiments of a fastener driveable into a substrate are provided. The fastener includes a head, a shank, and a helical thread formation. Portions of the shank and helical thread formations may be tapered. The outer diameter of the shank may decrease in a direction away from the head. An outer diameter of the thread formation may increase in a direction away from the head. The head may include a plurality of extending ribs. The helical thread formation may be formed with a plurality of grooves that are respectively each partially defined by a straight cutting edge. These improvements reduce torsional failure of the fastener from over tightening.
