Abstract: A fastener comprising a nut, a washer, and a shell that axially retains the nut and the washer together. In one embodiment, the shell axially retains the nut and the washer together, and has a lower wall axially retaining the washer to the nut in a first direction, and a s-shaped section retaining the nut to the washer in a second direction. In another embodiment, the shell has a bent section and a lower wall extending axially away from the bent section. The lower wall of the bent section retains the washer to the shell. In yet another embodiment, the shell comprises a base wall including a first bend, a first skirt depending away from the first bend, a second bend extending away from the second bend, a third bend extending away from the second bend, and a second skirt depending away from the third bend.

Abstract: In one embodiment, a threadless positioning pin includes a head end, a pilot end, a positioning shank, a retainer shank, and a keyway. In another embodiment, a threadless positioning retainer includes a first end, a second end, an exterior, and an interior with a key extending from an inner surface proximate the first end. In another embodiment, a threadless positioning fastener includes a threadless positioning pin and a threadless positioning retainer, including an interior with a key configured to ride in a keyway of the threadless positioning pin. In another embodiment, a method of joining assembly elements includes providing a primary element, advancing a threadless positioning pin through a positioning hole so that a key rides along a keyway, and rotating the threadless positioning pin so that the key engages the keyway to trap the primary element between the threadless positioning pin and a threadless positioning retainer.
