Abstract

A fastening system is configured to be securely fastened from one side of at least one component. The fastening system includes a fastener including a shaft having a distal end extending from a head. A first channel is formed through the fastener between the head and the distal end. A nut is configured to be connected to the fastener. The nut includes a second channel that is coaxially aligned with the first channel.

First claim

What is claimed is:

1. A fastening system that is configured to be securely fastened from one side of at least one component, the fastening system comprising:
a fastener including a shaft having a distal end extending from a head, wherein a first channel is formed through the fastener between the head and the distal end;
a nut that is configured to be connected to the fastener, wherein the nut includes a second channel that is coaxially aligned with the first channel;
a first securing device having a portion that extends into the first and second channels, wherein one of the first or second channels has a size and shape that conforms to an outer surface of the portion of the first securing device, wherein the outer surface has a hexagonal cross-section; and
a second securing device having an operative head that extends into the first channel, wherein the operative head rotationally constrains the fastener, wherein the operative head comprises a passage formed therethrough, and wherein the portion of the first securing device extends through the passage.

2. The fastening system of claim 1 , wherein at least a portion of the distal end includes external threads and the nut includes internal threads, and wherein the internal threads of the nut threadably engage the external threads of the fastener.

3. The fastening system of claim 1 , wherein one of the fastener or the nut is configured to be internally engaged through the first channel or the second channel to threadably secure the nut to the fastener.

4. The fastening system of claim 1 , wherein the second channel has a size and shape that conforms to the outer surface of the portion of the first securing device, and wherein the first securing device is configured to rotationally constrain the nut.

5. The fastening system of claim 1 , wherein the first channel includes a device-passage channel that is configured to allow the portion of the first securing device to move therein, and wherein the second channel includes a device-conforming channel that is configured to conform to a size and shape of the outer surface of the portion of the first securing device.

6. The fastening system of claim 1 , wherein the nut is configured to be secured to a surface of the at least one component prior to contact with the fastener.

7. The fastening system of claim 6 , wherein the nut is configured to be secured to the surface of the at least one component through at least one of an adhesive, bonding, and a filament.

8. A fastening system that is configured to be securely fastened from one side of at least one component, the fastening system comprising:
a fastener including a shaft having a distal end and external threads extending from a head, wherein a device-passage channel is formed through the fastener between the head and the distal end;
a nut including internal threads and a device-conforming channel, wherein the device-passage channel is coaxially aligned with the device-conforming channel, and wherein the internal threads of the nut engage the external threads of the fastener;
a first securing device having a portion that extends into the device-passage channel and the device-conforming channel, wherein the device-passage channel allows the portion of the first securing device to move therein, wherein the device-conforming channel has a size and shape that conforms to an outer surface of the portion of the first securing device, wherein the outer surface has a hexagonal cross-section and wherein the outer surface of the portion of the first securing device is configured to internally engage the nut through the device-conforming channel and rotate the nut relative to the fastener to threadably secure the nut to the fastener; and
a second securing device having an operative head that extends into the device-passage channel, wherein the operative head rotationally constrains the fastener, wherein the operative head comprises a passage formed therethrough, and wherein the portion of the first securing device extends through the passage.

9. A fastening method that is configured to be performed from one side of at least one component, the fastening method comprising:
positioning a distal end of a fastener with respect to a first side of the at least one component;
aligning the distal end of the fastener with an opening of the at least one component;
urging the distal end of the fastener into and through the opening of the at least one component from the first side;
connecting a nut to the distal end of the fastener at a second side of the at least one component that is opposite from the first side;
urging a portion of a first securing device from the first side of the at least one component into a first channel formed through the fastener and a second channel formed through the nut, wherein one of the first or second channels has a size and shape that conforms to an outer surface of the portion of the first securing device, wherein the outer surface has a hexagonal cross-section, wherein the urging comprises rotationally constraining one of the fastener or the nut by the portion of the first securing device, and wherein the rotationally constraining comprises using a second securing device having an operative head that extends into the first channel; and
extending the portion of the first securing device through a passage formed through the operative head of the second securing device.

10. The fastening method of claim 9 , further comprising:
rotationally constraining the other of the fastener or the nut that is not rotationally constrained by the first securing device; and
rotating the first securing device to rotate the one of the fastener or the nut that is rotationally constrained by the first securing device.

11. The fastening method of claim 10 , wherein the rotating the first securing device comprises threadably engaging internal threads of the nut with external threads of the fastener.

12. The fastening method of claim 9 , wherein the first channel includes a device-passage channel that is configured to allow the portion of the first securing device to radially move therein, and wherein the second channel includes a device-conforming channel that is configured to conform to a size and shape of the outer surface of the portion of first securing device.

13. The fastening method of claim 9 , further comprising securing the nut to the second side of the at least one component, and wherein the securing the nut to the second side of the at least one component comprises securing the nut to the second side through at least one of an adhesive, bonding, and a filament.

14. The fastening system of claim 1 , wherein the portion of the first securing device that extends into the first and second channels rotationally constrains one of the fastener or the nut.
