DIN 127 compliant with the standard spring washers, It is designed to prevent fasteners from loosening under vibration or dynamic loads. Its spiral spring structure provides an additional locking effect to the bolt-nut connection. It is an indispensable component for secure connections in many industries, from automotive to machine manufacturing.

DIN 127 spring washers are spiral-shaped washers. They provide a locking effect by applying compressive force to prevent loosening in bolt-nut systems.
Used to prevent loosening of connections in systems operating under vibration or dynamic loads. It is particularly preferred in automotive, machinery, rail systems, and equipment assembly.
They are usually made of carbon steel or spring steel. Stainless steel (A2/A4) versions are also preferred in areas where corrosion resistance is required. Surface coatings are selected according to the application area.
