Definitions

one or more of the top, bottom or side surfaces of a trapezoidal shaped nose and the corresponding walls of the socket are each bowed to fit together. These surfaces and walls have a gradual curvature to ease installation, enhance stability of the wear member, and resist rotation of the wear member about the longitudinal axis during use.
