Fixaball Metric Internal Shakeproof Washers Serrated BZP Zinc

For vibration-resistant fastening, Fixaball internal shakeproof lock washers feature overlapping serrations and a BZP zinc finish. These internal serrated washers are produced to DIN 6798A and suit a range of metric and imperial thread sizes, with the locking teeth positioned on the inside to leave a rounded outer edge.

The overlapping tooth pattern creates a deeper indent when tightened, making these washers suitable where a more secure, permanent joint is required. Zinc coated plain steel construction is intended for indoor use.
