Abstract:
1. A washer assembly comprising: a threaded fastener head engaging portion including 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; and a surface engaging portion including a slot and a surface engaging face, the slot extending through the surface engaging portion along a line extending through an axial center of the surface engaging portion, wherein 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, wherein the slot is defined by a noncircular opening in a plan view having a length greater than three times the diameter of the threaded fastener, and wherein the adjustable interface allows rotation of both the threaded fastener head engaging portion and the surface engaging portion relative to each other and the longitudinal length of the threaded fastener.
