Or FAST delivery Sat, Oct 10
DIN 6797A External Toothed Lock Washers are engineered to keep fasteners secure in vibrating and dynamic assemblies. Their external teeth bite into the mating surface, creating a locking action that resists loosening under cyclic loads. With broad material options and all sizes available, they provide a versatile, cost-effective solution for a wide range of applications.
Key features

- Available in multiple materials to suit environmental conditions and weight considerations
- All sizes offered to accommodate a broad spectrum of bolt diameters
- Simple, insert-and-seat installation that enhances assembly reliability
Materials & availability

- All sizes available to fit a wide range of fasteners
Ideal applications
- Machinery and equipment assemblies where vibration is a factor

How to choose the right washer
Selecting the right DIN 6797A washer depends on environment and load. For corrosion resistance and durability, choose stainless steel 304 for general use or 316 for salt exposure or marine-like conditions. If weight is a priority, consider aluminium. For budget-conscious projects in non-corrosive settings, carbon steel provides solid performance at a lower cost. Always ensure the washer size matches the bolt diameter and seating surface.
Installation tips
- Clean the mating surfaces before installation to maximize bite and seating
- Pair with a compatible bolt/nut and torquing protocol to achieve optimal locking performance
- Place the washer flat against the surface to ensure even distribution of clamping force
