Abstract

A broach style anti-rotation device for connected tubular members is described. In embodiments, the broach tool is inserted into a slot in an outer diameter surface of the pin, and teeth of the broach, which have a successively greater height when moving from the front to the tail of the broach, cut a slot in a surface of the box. Sidewalls of the broach and its teeth engage shoulders of each slot to prevent the rotation of the tubular members relative to each other.
