M4 Serrated Lock Washer 8.0mm (External Serrated) DIN 6798A A4 Stainless Steel WS6798A-M4-A4
The M4 Serrated Lock Washer 8.0mm (External Serrated) DIN 6798A A4 Stainless Steel (WS6798A-M4-A4) is an external-tooth serrated lock washer manufactured to DIN 6798A. Its outward-facing teeth are designed to bite into the mating surface when the joint is tightened, helping to increase resistance to rotational movement and loosening. Manufactured from A4 Stainless Steel, this washer is suitable for secure fastening applications where vibration resistance and corrosion resistance are required.
What are External Tooth Serrated Lock Washers?
External tooth serrated lock washers feature multiple teeth around the outside diameter of the washer. When compressed beneath a screw head or nut, the external serrations engage with the mating surface to create additional grip, helping to reduce unwanted loosening caused by vibration, movement or repeated loading.
