Abstract: A locking fastener assembly having a threaded member with a slot, a threaded rotatable fastener having a flange, the flange having a periphery and including at least one aperture extending through the flange, wherein the threaded rotatable fastener is engageable with the threaded member. The flange on the nut further includes a notch along the periphery of the flange. The locking fastener assembly also contains a retainer having an outer margin defining a plurality of notches and a protruding member, wherein the protruding member is engageable with the slot on the threaded member. A locking pin is also provided, wherein the locking pin is engageable with at least one of the threaded apertures in the flange and at least one of the notches in the retainer. In a preferred embodiment, the locking pin is aligned with at least one notch in the retainer when the notch on the flange is aligned with at least one notch on the retainer.

Abstract: A highly adjustable free spinning positively locking fastener assembly for threaded joints such as automotive or truck wheel assemblies includes a nut having a flange with a retainer washer captured on the nut flange via a locking bolt. The washer includes a tab received in a slot of a wheel spindle to permit the washer to move axially and prevent the washer from rotating. Bolt holes are located at unequally spaced opposed locations in the flange of the nut. A plurality of locking bolts locking the nut to the washer to prevent relative rotation so that neither the nut nor the washer can rotate relative to the spindle. The locking bolts are torsionally inserted into the locking bolt holes located in the nut. At least one locking bolt extends through at least one of the corresponding locking teeth of the washer. When the locking bolts are inserted into the locking bolt holes, the locking bolts engage the teeth of the washer to prevent the nut from rotating.

Abstract: A free spinning positively locking fastener assembly for threaded joints such as automotive or truck wheel assemblies includes a flanged nut with a retainer washer captured on the nut flange. The washer includes a tab received in a slot of a wheel spindle to permit the washer to move axially and prevent the washer from rotating. A pair of resilient locking clips normally lock the nut to the washer to prevent relative rotation so that neither the nut nor the washer can rotate relative to the spindle. The locking clips are released by engagement of a wrench socket with the wrenching structure of the nut so that the nut can be threaded to a desired position. When the wrench is removed, locking fingers on the clips engage the washer to prevent the nut from rotating. The clips are located at diametrically opposed wrenching flats of the nut, spaced from the corners of the wrenching structure.
