The nut and washer assembly of claim 22 with said resilient means including a plurality of circumferentially spaced resilient tab structures axially from said cage in a direction opposite to said fingers, each of said resilient tab structures including a radially outwardly extending locking protrusion defining said interference and being movable into said second portion of said washer bore to cooperate with said holding means to connect said nut structure and said washer member for free spinning relative to each other, said first bore portion of said washer bore being of a larger diameter than said second bore portion with said holding means including an annular ledge defined by the juncture between said first and second bore portions of said washer bore, said locking protrusion being axially engageable with said ledge for holding said nut structure and said washer member together, said washer bore including a third bore portion located adjacent said second bore portion and at the end of said washer in confrontation with said nut member, said third bore portion being chamfered to facilitate the resilient radial inward deflection of each of said tab structures as each of said locking protrusions engages said chamfered third bore portion, each of said locking protrusions having a generally flat, radially extending surface at its trailing end adapted to engage said ledge to facilitate holding said nut structure and said washer member together.

Claim 45
Dependent Claim
230 words
A nut and washer combination for providing a connectable assembly comprising: a nut structure including a heat treated nut member and an external cage, said nut member having a threaded bore, a washer member heat treated separately from said nut member and having a washer bore at least as large as said threaded bore, said washer bore having first and second bore portions, gripping means on said cage for gripping said nut member, connecting means on said cage and said washer member for connecting said nut structure to said washer member with said washer bore being generally concentric with said threaded bore after said nut member and said washer member have been heat treated as separate elements, said connecting means including flexible means operable in response to relative axial movement between said cage and said washer member in a first axial direction to a first axial position and being resiliently operable in one radial direction permitting said relative axial movement to continue in said first axial direction to a second axial position and being resiliently operable in another radial direction at said second axial position to resist relative axial movement of said cage and said washer member in a second axial direction, said connecting means holding said cage and said washer member together for free spinning relative to each other when said flexible means is at said second axial position.
