DIN6797-A External Tooth Lock Washer
DIN6797-A external tooth lock washer is a reliable locking component designed to improve fastening stability and prevent loosening in bolted connections. The DIN6797-A external tooth lock washer features external radial teeth that bite into the contact surfaces of the fastener and assembly part, increasing resistance against rotation caused by vibration and dynamic loads.
Manufactured from spring steel, stainless steel, or other suitable materials, the DIN6797-A external tooth lock washer provides excellent elasticity, reliable locking performance, and versatile application options. It is widely used in machinery, electrical equipment, automotive assemblies, industrial systems, and general mechanical fastening applications.
Product Overview
The DIN6797-A external tooth lock washer is engineered for applications requiring improved resistance against bolt and nut loosening. Its outer serrated teeth create a mechanical locking effect by gripping the underside of the fastener head or nut and the assembly surface.
Compared with standard flat washers, the DIN6797-A external tooth lock washer provides additional locking capability without requiring complex installation procedures. The external tooth design is especially suitable for applications where the washer needs to engage with larger bearing surfaces.
This washer is commonly selected by OEM manufacturers, equipment builders, and industrial suppliers requiring dependable fastening accessories.
