Description Internal shake proof lock washers manufactured from A4 stainless steel to DIN 6798J, designed to prevent fasteners from loosening under vibration and dynamic loads. The internal serrations bite into the mating surfaces to create a secure locking action while maintaining tension within the assembly.
Manufactured from corrosion resistant A4 (316) stainless steel, these washers provide superior durability and resistance to corrosion, making them particularly suitable for marine, coastal and other harsh environments where reliable locking performance is required.
