A fully stabilized excavator tooth attachment. An excavator tooth includes a nose-receiving pocket bounded by an inner end, upper and lower, and opposing side walls, the end wall having a nose-engaging interface surface formed orthogonal to a longitudinal axis of the tooth, at least one of the side walls having a fastener opening formed therethrough, and each of the upper and lower walls having two spaced apart nose-engaging interface surfaces formed thereon substantially parallel to each other. Another excavator tooth includes side walls having generally planar nose-engaging interface surfaces formed therein, one surface resisting rotation of the tooth about the longitudinal axis in one direction, and another interface surface resisting rotation of the tooth in an opposite direction. An attachment system includes a fastener configured for releasably securing the tooth on the nose, the fastener having a thread which is eccentric relative to a body of the fastener. |
