1. A wear member for an excavating bucket comprising a pair of sidewalls, converging walls converging toward a front wear portion to contact materials to be excavated during digging by the excavating bucket, and a rearwardly opening socket for receiving a nose secured to an excavating bucket, the socket having a longitudinal axis and being defined by (i) converging surfaces adapted to overlie converging walls of the nose, (ii) side surfaces adapted to overlie sidewalls of the nose, (iii) a groove on each of the side surfaces for receiving rails formed on the nose, each said groove being defined by one of the converging surfaces and a lateral surface extending inward from one of the side surfaces, each said lateral surface being inclined in an axial direction to the longitudinal axis and defining a bearing surface to contact one of the rails to resist loads during use, and each said lateral surface being inclined to the longitudinal axis in the same general direction as the converging surface that the lateral surface faces and (iv) a front end including opposite front stabilizing surfaces forward of the converging surfaces and extending between the side surfaces, each of the front stabilizing surfaces extending generally parallel to the longitudinal axis in the axial direction to contact complementary surfaces on the nose to resist loads during use.
