Serrated Lock Washer 6798


DIN 6798 Metric Serrated Lock Washers are Washers with a serrated surface that is used to prevent threaded fasteners from loosening. As the fastener is tightened the serrations of the washer grip into the head of the fastener and the mating surface increasing the friction force which help the fastener resist rotational movement. Serrated Lock Washers work very well on soft materials.
DIN 6798 Form A has External Teeth
DIN 6798 Form J has Internal Teeth
DIN 6798 Form V is for use with countersunk head screws

Metric & Multistandard Components Corp. offers DIN 6798 Metric Star Lock Washers in Zinc Plated Steel, and Stainless Steel.
