Abstract

A bolt configured for preventing loss of the bolt during removal can include a bolt head, a bolt shaft extending from the bolt head in an axial direction, the bolt shaft including threads, and a bolt capture channel defined through the bolt head and the bolt shaft in the axial direction. The bolt capture channel can include a head opening and shaft opening.

First claim

What is claimed is:

1. A bolt configured for preventing loss of the bolt during removal, comprising:
a bolt head;
a bolt shaft extending from the bolt head in an axial direction, the bolt shaft including threads;
a bolt capture channel defined through the bolt head and the bolt shaft in the axial direction, the bolt capture channel including a head opening and shaft opening; and
a cable disposed in and through the bolt capture channel, wherein the cable is disposed through the bolt capture channel of a plurality of bolts.

2. The bolt of claim 1 , wherein the bolt capture channel is defined centrally through the bolt head and the bolt shaft.

3. The bolt of claim 1 , wherein a bolt shaft end of the cable includes a stop member configured to contact the bolt shaft to prevent the cable from being pulled out of the bolt capture channel.

4. The bolt of claim 3 , wherein the stop member is larger than the bolt capture channel such that the stop member cannot fit through the bolt capture channel.

5. The bolt of claim 4 , wherein the stop member is a swage of the bolt shaft end of the cable.

6. The bolt of claim 3 , wherein the bolt head end of the cable is configured to be connected to a structure that the bolt attaches to.

7. The bolt of claim 1 , wherein the bolt head includes a hex shape.

8. A method, comprising:
fabricating a bolt to include:
a bolt head;
a bolt shaft extending from the bolt head in an axial direction, the bolt shaft including threads; and
a bolt capture channel defined through the bolt head and the bolt shaft in the axial direction, the bolt capture channel including a head opening and shaft opening;

inserting a cable into the bolt capture channel;
disposing a stop member on the bolt shaft end of the cable; and
inserting the cable through a plurality of bolts.

9. The method of claim 8 , wherein disposing a stop member includes swaging an end of the cable to be larger than the bolt capture channel.

10. The method of claim 8 , wherein fabricating the bolt includes drilling the bolt capture hole through the bolt head and the bolt shaft.

11. A system, comprising:
a structure having a bolt hole;
a bolt configured to be disposed in the bolt hole having:
a bolt head;
a bolt shaft extending from the bolt head in an axial direction, the bolt shaft including threads; and
a bolt capture channel defined through the bolt head and the bolt shaft in the axial direction, the bolt capture channel including a head opening and shaft opening; and

a cable disposed through the bolt capture channel, wherein the cable is disposed through the bolt capture channel of a plurality of bolts, wherein a bolt shaft end of the cable includes a stop member configured to contact the bolt shaft to prevent the cable from being pulled out of the bolt capture channel, wherein the bolt head end of the cable is attached to the structure.

12. The system of claim 11 , wherein the stop member is larger than the bolt capture channel such that the stop member cannot fit through the bolt capture channel.

13. The system of claim 12 wherein the stop member is a swage of the bolt shaft end of the cable.

14. The system of claim 13 , wherein the bolt is threaded into the bolt hole.

15. The system of claim 14 , wherein the bolt head includes a hex shape.
