Abstract
A washer assembly includes a threaded fastener head engaging portion and a surface engaging portion. The threaded fastener head engaging portion includes a head engaging face configured to lie in a plane substantially perpendicular to a longitudinal length of a threaded fastener passed through an opening at an axial center of the threaded fastener head engaging portion. The surface engaging portion includes a slot and a surface engaging face. The slot extends through the surface engaging portion along a line extending through an axial center of the surface engaging portion. An adjustable interface is defined between the surface engaging portion and the threaded fastener head engaging portion to enable the slot to receive the threaded fastener such that the surface engaging face lies parallel to a surface that is not perpendicular to the longitudinal length of the threaded fastener.
