A wear runner assembly is attached to a surface of an excavating bucket and serves to protect a portion of the surface from abrasion wear during use of the bucket. The assembly includes a base member, a wear runner member, a pair of bolts and a pair of conical locking nuts. The base member is welded to the surface and has a pair of undercut slots that captively retain the head portions of the bolts, with the bolt bodies being transverse to the surface and projecting outwardly beyond the outer side of the base member. The wear runner member is mounted on the base member by moving the wear runner member toward the base member in a direction transverse to the surface in a manner causing the outwardly projecting bolt body portions to enter and be recessed within a pair of openings formed through the wear member, and also causing projections on the base member to be complementarily received within recesses formed in the wear runner member. Finally, conical locking nuts are threaded onto the bolt bodies recessed within the wear runner member openings to releasably hold the wear runner member on the base member. The interlock between the base member projections and the wear runner member recesses prevents operating loads imposed on the assembly from moving the wear runner member relative to the base member parallel to the protected surface to thereby prevent the bolts from being sheared by such operating loads.
