Abstract:
1. A retainer sized, constructed and arranged for retaining a bolt having a threaded shank, the retainer comprising: a first base portion having a bottom surface in a first plane; and a second base portion comprising a living hinge portion extending inwardly and upwardly from the first base portion and above the first plane, and more than two fingers extending in a continuously inclined upward and inward direction from the second base portion, each finger having a deformable tip section having at least one thread engaging ridge, each finger and deformable tip section disconnected separated from an adjacent finger and deformable tip section, the deformable tip sections being disposed in a second plane above the first plane and above the second base portion and together defining a bolt bore aperture sized to receive the threaded shank of the bolt, the fingers are constructed and arranged so that the thread engaging ridges on the deformable tip sections deflect in use upwardly and outwardly away from the threaded shank of the bolt when the retainer is pushed in a downward direction from the second plane towards the first plane over the threads of the threaded shank, and deflect in use downwardly and inwardly when the retainer is tightened by turning the retainer over the bolt.
