Patent ID: 7950887

Claim:
A fastener assembly comprising: a fastener element with a head section constructed to be engageable with a driving tool, a threaded shank section with threads having a pitch and an integrally formed distal end section; said distal end section having a recess therein; a retention device member secured to said distal end section; said retention device engaging said recess and positively engaged onto said distal end section; said retention device having at least one outer extension flange and angled radially outwardly and axially toward said head section from its base, said base having a proximal edge and distal edge; said at least one flange extending 360° about said retention device; said retention device having a securement collar extending about and along said distal end section of said fastener element toward said head section from said proximal edge of the base of said outer flange, said securement collar having an outer diameter that is of reduced size relative to a diameter of said distal edge of said base of said flange; said retention device member engageable to a fastener receiving member when said distal end section is inserted into a hole in said fastener receiving member; and said retention device being sized to engage an inside wall of said hole in said fastener receiving member to provide insertion of said fastener assembly in said hole with a low entry force and to resist higher exiting forces.
