Abstract
A belt fastener is provided where, in one form, a washer is assembled on a bolt that extends through a recessed aperture in a lower plate of the belt fastener. An inclined cup wall of the lower plate extends toward the recessed aperture and is for seating of the bolt head thereagainst with the shank extending through the aperture. In accordance with one aspect, the washer is sized to fit into the area of the aperture so that when an upper plate is applied to the belt ends for clamping the belt ends between the upper plate and the lower plate, the washer can be shifted into the aperture area and, if necessary, into the recess formed by the cup. In this manner, the washer is not extruded over the lower cup in contrast to larger washers of prior belt fasteners.
