DIN6797-J Internal Tooth Lock Washer
DIN6797-J internal tooth lock washer is a precision locking component designed to improve fastening stability and prevent loosening in threaded connections. The DIN6797-J internal tooth lock washer features inward-facing serrated teeth that grip the fastener surface and create resistance against rotation caused by vibration, shock, and dynamic loads.
Manufactured from high-quality spring steel or stainless steel, the DIN6797-J internal tooth lock washer provides reliable locking performance, good elasticity, and durable mechanical properties. It is widely used in electrical equipment, machinery, automotive components, control systems, and industrial assemblies requiring secure and compact fastening solutions.
Product Overview
The DIN6797-J internal tooth lock washer is engineered for applications where the washer must remain within the outer diameter of the fastener. Its internal serrated teeth engage with the bolt head or nut surface, while the outer edge remains smooth and compact.
Compared with external tooth washers, the DIN6797-J internal tooth lock washer is especially suitable for applications with limited installation space or where a clean external appearance is required.
The toothed locking structure increases friction and improves resistance against loosening, making it a practical solution for many industrial fastening applications.
