Stainless Steel Knurled Disc Washers
Radial knurl teeth on the contact face cut through paint, anodising and oxide film so a bolted joint keeps electrical continuity between PV module frames, rails and support structures. The disc-spring section also stores preload, so the connection stays tight through thermal cycling. Washers are supplied in stainless steel with a pickled finish; tooth pattern, outer diameter and thickness follow the selected drawing.
