Flanged hillside washers are used to distribute loads when attaching cross-bracing rods or cables to structural beams.  The flange is designed to spread the force across the structural beams.  The curved top of the washer allows for rods to pass through and be secured at different angles.  A nut is used to secure the rod on the backside of the washer.  The bottom of the hillside washer is flat so they can sit flush with the structural beams.
