US Patent 7959392 U-nut fastener assembly

A U-nut fastener assembly includes a U-nut fastener including a first arm member, a second arm member formed unitarily with the first arm member, a bite portion formed unitarily between the first and second arm portions such that the first arm member, the second arm member, and the bite portion are oriented to form a substantially U-shape. The nut includes a single helical thread having a proximal end and a distal end that are separated by a longitudinal gap. The U-nut assembly also includes a fastener device adapted to be received within the U-nut fastener. The single helical thread has a proximal end and a distal end and a gap disposed between the proximal and distal ends. The U-nut assembly is molded from a plastic material to include an anti-reverse feature that inhibits the fastener device from loosening with respect to the U-nut fastener. The anti-reverse feature is also adapted to provide a tactile indication to an operator installing the U-nut assembly.
