Fastener with zoned, varying wave-form thread

A fastening assembly comprising:

• a threaded fastener having a shank with a tip and a head configured for engagement by an associated driving tool, the head disposed on the shank opposite the tip, the shank having a helical thread formed thereon, the thread extending from about the tip to about the head, and defining a plurality of zones, each zone having a plurality of individual threads extending 360 degrees about the shank, and wherein a leading thread in each zone is formed with a wave-form profile defined as a continuous sine wave pattern over the entire 360 degrees thereby defining an amplitude, such that starting with the leading thread closest to the head, each amplitude of each leading thread is greater than the amplitude of each prior leading thread which is closer to the tip;
• and
• a female component for threadedly receiving the threaded fastener, the female component having an expandable helical thread formation that is capable of having a final dimension after receiving the threaded fastener that is less than the smallest of the amplitudes of the wave-form profile threads, such that a pressure flank and a trailing flank of each leading thread of the threaded fastener are configured to alternately engage the helical thread of the female component.
