What are Internal Tooth Serrated Washers?

M10 Internal Tooth Serrated Washers are a type of locking washer made to DIN 6797J standard. Unlike external toothed washers, the teeth are located on the inner circumference, which makes them ideal for applications where the fastener head must remain smooth or unobstructed. When compressed during fastening, the internal serrations dig into the surface and the fastener, providing resistance against loosening caused by vibration, thermal cycling, or motion. These washers are especially effective when used with softer materials like aluminium or plastics, where surface grip is essential.
