Abstract:
A stripped spark plug extraction tool device removes stripped spark plugs from an engine. The device includes a tubular member. A tubular member socket extends into a bottom end of the tubular member and is defined by a plurality of faces extending into the bottom end of the tubular member. A plurality of extensions extends from the faces of the tubular member socket inwardly toward a center of the tubular member socket. The extensions are configured for engaging a perimeter edge of a stripped portion of a spark plug to extract the stripped spark plug from an engine. A housing has a top face, a bottom face and a peripheral wall extending between the top face and the bottom face. The peripheral wall comprises a plurality of planar faces wherein an outer surface of the peripheral wall of the housing is configured to be engaged and rotated by a wrench.
