Threaded fastener having a thread crest greater than its thread root and v angles on the crest and root

A fastener, comprising:

• a shaft having a first end including means to rotate said shaft,
• said shaft having a thread pattern defined by a thread projecting from an outer periphery of said shaft and spiraling along its length, and a root gap separating adjacent threads;
• said thread defined by an upper flank, a lower flank, a root adjacent said shaft and crest remote from said shaft,
• said upper and lower flanks being separated by a “V” shaped indentation and diverging outwardly from each other away from said root and defining a dovetail, wherein an apex of said “V” shaped indentation has an acute angle;
• and
• a “V” shaped protrusion protruding from said shaft in said root gap, the “V” shaped protrusion having a shape complementary to said “V” shaped indentation.
