Fastener removal aid devices

A fastener removal aid device for assisting with the removal of a frangible, self-locking fastener having a pin having a head and an externally threaded shaft, and a collar configured to be torqued onto the externally threaded shaft, the fastener removal aid device comprising:

• a body having at least one drill opening positioned axially along a central axis of the body and at least one additional fastener opening sized to receive a portion of the self-locking fastener, where the at least one drill opening is positioned to axially align with the pin of the self-locking fastener when the body is positioned on either an end of the self-locking fastener with the head or an end of the self-locking fastener with the collar, and the at least one additional fastener opening is off-center from a central axis of the at least one additional fastener opening such that the pin is avoided when drilling the collar so as to loosen the collar to enable its separation from the pin.

A fastener removal aid device for assisting with the removal of a frangible, self-locking fastener having a pin having a head and an externally threaded shaft, and a collar configured to be torqued onto the externally threaded shaft, the fastener removal aid device comprising:

• a body having at least one drill opening positioned along the body and at least one additional fastener opening sized to receive the collar of the fastener, where the at least one drill opening is positioned to axially align with the collar of the self-locking fastener when the body is positioned on the self-locking fastener,
• whereby the at least one drill opening is positioned off-center from a central axis of the at least one additional fastener opening such that the pin is avoided when drilling the collar.

A method for removing a frangible, self-locking fastener having a pin having a head and an externally threaded shaft and a collar configured to be torqued over the externally threaded shaft, that secures two surrounding parts, the method comprising:

• positioning a fastener removal aid device on either an end of the self-locking fastener with the head or an end of the self-locking fastener with the collar, the fastener removal aid device having an opening sized to receive at least a portion of the self-locking fastener securing the two surrounding parts, where the fastener removal aid device further includes a body having at least one drill opening sized to receive a drill bit and align the drill bit with the received portion of the self-locking fastener securing the two surrounding parts;
• and
• drilling through the at least one drill opening with a drill bit to remove a portion of the collar of the self-locking fastener, whereby the at least one drill opening is positioned off-center from a central axis of the received portion of the self-locking fastener opening such that the removed portion of the self-locking fastener is entirely from the collar.
