Stuck threaded member extractor tool and extraction methods
Abstract
Disclosed is a tool having a tapered first portion configured to translate a rotational force to the stuck member, a second portion connecting with the first portion and configured to translate the rotational force to the tapered first portion, a planar tip at an end of the first portion and perpendicular to a central axis passing through the first portion and the second portion, a plurality of left-handed splines extending helically around the central axis from the tip toward the second portion, a driver engaged with the second portion and configured to receive a third rotational force from a mechanical manipulator, and a leak seal connected to the driver and configured to form a seal around the stuck member and at least a portion of the driver and prevent gases opposite the stuck member from escaping.
