At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 6798 V. Serrated (toothed) lock washers, Form V = countersunk external-tooth (conical / dished) type. The dished body with external serrations bites into both the bolt head and the joint face to resist loosening under vibration; suits countersunk-style bearing surfaces. Companion forms: A (flat external tooth), I/J (internal tooth). Sizes M3-M12.
