Patent ID: 7465137

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 circumferential groove; a retention device member secured to said distal end section; 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; said retention device engaging said circumferential groove in proximity to a proximate end of the retention device to be positively engaged onto said distal end section and being adheredly molded to the distal section; said retention device having at least one outer extension flange with a base axially aligned over said groove section and said flange being angled radially outwardly and axially toward said head section; said groove section extending axially beyond said flange in the direction of said head section; 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.
