Multi-piece fastener including a shell

A fastener comprising:

• a nut including a head, a flange extending away from the head and including an upper surface and a lower surface, and a nut through hole having a central axis extending therethrough;
• a washer including a first surface and a second surface, the first surface being adjacent the lower surface of the nut;
• and
• a shell including:
• a bent section, comprising:
• an upper portion retaining the nut within the shell;
• a lower portion adjacent to and in contact with the first surface of the washer, and
• a middle portion extending between the upper portion and lower portion, and
• a lower wall extending axially away from the lower portion of the bent section, the lower wall and lower portion of the bent section retaining the washer to the shell.

A stamped metal washer and nut retention shell, comprising:

• a base wall including
• an upper surface,
• a lower surface, and
• a base wall inner diameter extending between the upper and lower surfaces;
• a first bend extending away from the base wall;
• a first skirt depending away from the first bend and including
• a first skirt inner diameter greater in size than the base wall inner diameter, and
• a first skirt outer diameter;
• a second bend extending away from the first skirt;
• a third bend extending away from the second bend;
• and
• a second skirt depending away from the third bend and terminating in a bottom surface of the shell, and including
• a second skirt inner diameter greater than the first skirt outer diameter, and
• a second skirt outer diameter,
• wherein the second skirt is straight cylindrical from the third bend to the bottom surface.

A washer and nut retention shell, comprising:

• a base wall including
• an upper surface,
• a lower surface, and
• a base wall inner diameter extending between the upper and lower surfaces;
• a first bend extending away from the base wall;
• a first skirt depending away from the first bend and including
• a first skirt inner diameter greater in size than the base wall inner diameter, and
• a first skirt outer diameter;
• a second bend extending away from the first skirt;
• a third bend extending away from the second bend;
• and
• a second skirt depending away from the third bend and including
• a second skirt inner diameter greater than the first skirt outer diameter, and
• a second skirt outer diameter,
• wherein the first skirt and the second skirt are configured to concentrically retain a nut and a washer within the shell so that the nut can freely rotate with respect to the washer and the shell.
