Indicating washers may include bumps and underlying dimples configured to control compression of the indicating washer during installation. Each bump may include a tapered triangular shape and may be asymmetrical with respect to each underlying dimple. Methods of operating an indicating washer system may include providing progressive compression along trailing, top, and leading ramp surfaces. Methods of manufacturing may include forming a washer from a metal sheet with a tool having an inner cutting edge, an outer cutting edge, a triangular punch, and a stop.
