GB861.2 DIN6798J A2-70 304 Stainless Steel Internal Toothed Serrated Lock Washer Gasket M2–M24

DIN6798J / GB861.2 standard 304 stainless steel internal toothed (serrated) lock washers. The internal teeth bite into both the bolt head and the workpiece surface, providing superior anti-loosening resistance compared to split lock washers. The internal tooth design keeps the outer edge smooth, making these ideal for applications requiring a clean outer appearance or electrical grounding contact.
