Kind Code:
B2
Abstract:
A stud or nut removing tool has a hollow tubular casing with a thin wall internally formed into at least one lobe, each lobe constituting an inclined cam face and extending axially from an open lower end to a partially closed upper end. At least one generally cylindrical, elongated roller, or pin, is provided, either resiliently urged outwardly in contact with one of said lobes by a central spring means or loosely held by rib and groove means. Each roller is otherwise free to roll along the inclined cam face in either direction and to tilt when the lower portion of the roller engages a stud or nut for removal thereof. The outer ends of the rollers are exposed to slidably receive the stud or nut and the tips of the rollers are flush with the rim of the casing.
