Abstract

An anti-rotation device for securing fasteners is disclosed. The device is deployed over a fastener, such as a hex nut. A plurality of panels engage the top and sides of the fastener. A wire is attached to the device, and is secured to an adjacent hard point. The tension in the wire prevents the nut from rotating but requires no modification to the hex nut, and can be removed easily if desired. A plurality of tabs located about the device provide additional gripping strength and further prevent undesired rotation of the fastener. Easy inspection of the device and its connection wire allows a user to determine that the fastener is still secure, especially desirable where the fastener is in limited access areas.

Claims

1. An anti-rotation device to be inserted over a fastener comprising:

a first plurality of panels disposed radially about an axis;

a second plurality of panels disposed perpendicularly to and formed from said first plurality of panels about said axis;

a plurality of tabs for gripping adjacent surfaces; and

a wire attached to said device.

2. The anti-rotation device of claim 1, wherein said device is constructed of metal.

3. The anti-rotation device of claim 1, wherein said device further comprises a plurality of tabs located about said device for engagement between said device and said fastener.

4. The anti-rotation device of claim 1, wherein said device is constructed of a polymer material.

5. The anti-rotation device of claim 1, wherein said device is chemically treated to resist corrosion.

6. The anti-rotation device of claim 1, wherein said wire is constructed of metal.

7. The anti-rotation device of claim 1, wherein said wire is constructed of resin.

8. An anti-rotation device to be inserted over a socket-head fastener, comprising:

a cylinder;

a plurality of panels attached to one end of said cylinder, and perpendicular to said cylinder;

a plurality of tabs for gripping adjacent surfaces; and

a wire attached to said cylinder.

9. The anti-rotation device of claim 8, said panels further comprising a plurality of bends so as to engage a plurality of sides of said socket-head fastener.

10. The anti-rotation device of claim 8, wherein said device is constructed of metal.

11. The anti-rotation device of claim 8, wherein said device is constructed of a polymer material.

12. The anti-rotation device of claim 8, wherein said device is chemically treated to resist corrosion.

13. The anti-rotation device of claim 8, wherein said wire is constructed of metal.

14. The anti-rotation device of claim 8, wherein said wire is constructed of resin.
