FASTENER REMOVAL AID DEVICES

摘要

A fastener removal aid device for removing a fastener, such as a Hi-Lok® type fastener, is provided that includes at least one drill opening and a fastener opening for receiving at least part of the fastener. The fastener opening of the fastener removal aid device may be designed to fit over either the collar or the protruding head of the fastener. The drill opening of the removal aid then aligns with a portion of the fastener to provide a guide for precision drilling into the correct position of the fastener. The drill opening may be centered through the fastener removal aid device in axially alignment with the pin of the fastener when the fastener removal aid device is positioned on the fastener. The drill opening may be centered to drill into either the threaded shaft end or head end of the fastener. Alternatively, the drill opening may be positioned to laterally break the fastener by placing one or more drill openings on the sides of the fastener removal aid. The drill opening may also be positioned to axially break the collar by positioning at least one drill opening off-center to drill axially into the collar when the fastener removal aid device is positioned over the collar of the fastener.
