Claim 0:
1. A molded screw comprising:
a sleeve portion adapted to receive a pole; and,
a conically shaped shank extending from the sleeve to a lower end of the molded screw, the conically shaped shank further comprising:
a high thread comprising:
crest portions; and,
recessed portions alternating in between the crest portions, the recessed portions curving inwardly towards the conically shaped shank and smoothly transitioning into the crest portions along a length of the high thread to reduce friction of the molded screw during digging and prevent unwanted movement of the molded screw when secured in a substance; and,

a low thread,

wherein the high thread and the low thread extend from the sleeve portion to the lower end of the molded screw in an alternating spiral fashion,
wherein the recessed portions comprise a peripheral surface that is smooth along a length of the conically shaped shank, the recessed portions to reduce an undercut of the high thread and facilitate the removal of the molded screw from a mold and to provide an area in which the substance can flow during rotation of the molded screw,
and wherein the peripheral surface is positioned between a first surface and a second surface, and wherein each of the first surface and the second surface extend from the peripheral surface to opposed sides of the high thread.
