GB862.2 DIN6798A A2 304 Stainless Steel External Serrated Toothed Lock Washer Gasket M2.5–M24

DIN6798A / GB862.2 standard 304 stainless steel external toothed (serrated) lock washers. The external teeth on the outer edge bite into both the bolt head and the workpiece surface, providing superior anti-loosening resistance. The larger tooth contact area of external teeth vs. internal teeth makes these ideal for soft materials and large-diameter bolt heads.
