  • Screw form anchor device
    Patent number: 6824331
    Abstract: A screw form anchor device (10) intended for screwed penetration into a host material. The anchor device (10) includes a body (11) having a manipulating end (12) and a distal end (13). A screw thread (22) is formed by a plurality of tapering angular helix thread forms (22a) which extend from the distal end. Each angular helix thread form (22a) has an outward facing surface (24) and, relative to the distal end, a downward facing surface (25). In the preferred form an emergent helix thread (26) commences from a point distant from the distal end (13). This emergent helix thread (26) extends toward the manipulating end (12) of the body (11).
