ABSTRACT:
A threaded fastener includes a shank having a tip and a head configured for engagement by an associated driving tool. The fastener is configured for use with an associated threaded opening. The head is disposed on the shank opposite the tip. The shank has a helical thread formed thereon. The thread extends from about the tip to about the head and defines a plurality of zones. Each zone has a plurality of individual threads extending 360 degrees about the shank. A leading thread in each zone is formed with a wave-form profile having an amplitude that is greater than the amplitude of each prior leading thread. In one embodiment, threads other than the leading thread in each zone do not have an amplitude as great as their respective leading threads. A fastening assembly is also disclosed.
