Abstract:

A fastener retainer removal tool comprises a handle, a shank extending from the handle, and a tip at the distal end of the shank. The tip has a narrow portion and a wide portion divided by a slot that is tapered outward on one side. The other end of the slot is enlarged to hold a workpiece inside the slot. The narrow portion of the tip is used for guiding safety wire and cotter keys into the slot. The wide portion of the tip is used as a lever to assist in bending thick cotter keys. The present invention relates to hand tools for mechanical assembly and maintenance. More specifically. but without limitation thereto, the present invention relates to a screwdriver adapted to removing safety wire and cotter keys from bolt fasteners. Several hand tools are used for removing safety wire and cotter pins from fasteners commonly used in aircraft and other machinery. Examples of such tools are diagonal cutters, needle nose pliers. duckbill pliers. scribes. awls, and in some cases hammer and chisel. Some disadvantages of these tools are that often more than one tool is required and that often there is not enough space around the fastener to operate these tools. Accordingly there exists a continuing need for a single tool that can manipulate safety wire and cotter keys in confined spaces.
