A wear plate assembly for mounting on a substrate to be protected includes a support plate having a first surface and an opposing second surface and a wear plate having a wear surface and an opposing attachment surface affixed to the first surface of the support plate, wherein the wear surface is a continuous, uninterrupted surface. The assembly also includes a shaft having a base portion attached to the second surface of the support plate, a head portion distal from the base portion and a groove formed between the base portion and the head portion. The assembly also includes a retainer spring adapted to be received in the groove on the shaft, wherein the retainer spring includes a plurality of compressible tabs configured for cooperating with the substrate to releasably attach the wear plate assembly to the substrate.
