Rivet fastener assembly and method of use thereof

1. A fastener assembly, comprising:

a fastener body including a collar and a receiving column having a protrusion on an inner surface thereof, the fastener body defining a longitudinal axis; and

a pin including a threaded section,

wherein the protrusion is configured to engage and cooperate with the threaded section,

wherein a projection extends from an inner annular wall of the collar, away from the receiving column, parallel to the longitudinal axis, and into a void, such that a longitudinal gap is formed laterally between the projection and the inner annular wall, and

wherein the receiving column further includes a first set of legs that are configured to fold above a second set of legs with respect to the longitudinal axis.

2. The fastener assembly of claim 1 , wherein the pin is configured to be positioned within the receiving column.

3. The fastener assembly of claim 1 , wherein the first and second sets of legs are configured to fold upon rotation of the pin.

4. The fastener assembly of claim 3 , wherein the receiving column includes a lower distal end, and wherein the protrusion cooperates with the threaded section to move the lower distal end relative to the pin upon rotation of the pin.

5. The fastener assembly of claim 4 , wherein the first and second sets of legs are configured to collapse upon rotation of the pin.

6. The fastener assembly of claim 1 , wherein the pin remains engaged with the projection throughout rotation thereof.

7. The fastener assembly of claim 6 , wherein the receiving column includes four protrusions equally spaced around a circumference of the inner surface of the receiving column.

8. The fastener assembly of claim 1 , wherein an annular rim extends between the first set of legs and the second set of legs, and wherein the annular rim includes a plurality of recessed surfaces.

9. A fastener assembly, comprising:

a fastener body including a collar and a receiving column, the fastener body defining a longitudinal axis; and

a pin,

wherein the receiving column is configured to collapse upon rotation of the pin,

wherein a projection extends from an inner annular wall of the collar and into a void,

wherein the receiving column further includes a first set of reinforcing legs that are configured to fold above a second set of reinforcing legs with respect to the longitudinal axis, and

wherein an annular rim extends between the first set of reinforcing legs and the second set of reinforcing legs.

10. The fastener assembly of claim 9 , wherein the receiving column includes a distal end wall and the collar includes a bottom surface, and wherein the receiving column extends between the bottom surface and the distal end wall.

11. The fastener assembly of claim 10 , wherein the pin includes a head.

12. The fastener assembly of claim 11 , wherein a distance between the head of the pin and the distal end wall of the receiving column in the collapsed state is smaller than a distance between the head of the pin and the distal end wall of the receiving column in an initial state.

13. The fastener assembly of claim 12 , wherein a distance between the head of the pin and the bottom surface of the collar in the collapsed state is equal to a distance between the head of the pin and the bottom surface of the collar in an initial state.

14. The fastener assembly of claim 13 , wherein the first and second reinforcing legs are configured to fold upon rotation of the pin.

15. The fastener assembly of claim 14 , wherein a lower annular rim extends between the second set of reinforcing legs and the distal end wall.

16. The fastener assembly of claim 15 , wherein the annular rim comprises a recessed surface.

17. A fastener assembly, comprising:

a fastener body including a collar and a receiving column; and

a pin including a head,

wherein the receiving column is configured to collapse upon rotation of the pin,

wherein a distance between the head of the pin and a bottom surface of the collar in the collapsed state is equal to a distance between the head of the pin and the bottom surface of the collar in an initial state, and

wherein a projection extends from an inner annular wall of the collar and into a void, a bottom surface of the head extending radially outward of a top surface of the projection and radially inward of the inner annular wall.
