Serrated Safety Washers, External and Internal Lock Washers Din 6798 A&J

Used with threaded fasteners (for example, a bolt or a nut), External or Internal serrated
washers are typically used to prevent the fastener from loosening, caused by
vibration. The serrations are situated on the External or Internal circumference, and
effectively ‘bite’ into the fastener and substrate surfaces as the fastener is
tightened.
