Metric Din 6798A External Tooth Serrated Lockwasher Zinc Cr+3
Metric External Tooth Serrated Lock Washers manufactured to DIN 6798A and finished with Zinc Cr+3 are engineered to deliver superior locking performance through a combination of serrations and outward-facing teeth. This design enhances friction and bite against the mating surface, helping prevent fastener loosening caused by vibration, shock, or dynamic loads. The Zinc Cr+3 finish provides clean appearance and reliable corrosion resistance for general industrial and light outdoor environments.
DIN 6798A serrated lock washers offer excellent holding strength and are ideal for use with metric screws and bolts in electrical assemblies, machinery, appliances, and precision equipment. Their serrated, external-tooth profile increases grip on a variety of materials, especially softer or coated surfaces. With durable zinc plating and consistent metric sizing, these washers provide dependable, long-term fastening security in demanding applications.
