Abstract
Abstract Shoes for worn or new paving augers that can be installed over and in conformity with the paving auger to provide additional life for the auger. A first wall of the auger shoe is formed with a bore, an enlarged diameter bore and a countersunk hole so as to accommodate either a cap screw with a hexagonal head, a plow bolt with a square shoulder, a bolt with a flat head, a bolt with a hexagonal head, a hexagonal nut, a flat head screw or a flat head socket type screw, and still provide a flush seat for the fastener in the front wall of the auger shoe to thereby maintain an unobstructed surface on the front wall of the auger shoe. In addition, the auger shoes can be installed against both the front and back walls of the auger.
