Metric Din 6797J Internal Tooth Lockwasher Zinc Cr+3
Metric Internal Tooth Lock Washers manufactured to DIN 6797J with a Zinc Cr+3 finish are designed to provide secure fastening by using inward-facing teeth that grip both the fastener head and the mating surface. This design increases friction and helps prevent loosening caused by vibration, movement, or thermal cycling. The Zinc Cr+3 plating offers clean appearance and dependable corrosion resistance suitable for indoor and light outdoor applications.
DIN 6797J internal tooth lock washers are ideal for use in electronics, appliances, control panels, and machinery where a smooth outer edge is preferred to avoid interference with surrounding components. The internal-tooth configuration ensures strong locking action while maintaining a compact profile. With precision metric sizing and a protective zinc finish, these washers provide reliable, long-lasting performance across a wide range of fastening applications.
