Shakeproof Washers (Tooth Lock Washers)

We now supply both External Tooth Lock Washers & Internal Tooth Lock Washers. These type of Washers can also be known as Shakeproof Washers.
These type of Washers are supplied to DIN 6797 and are finished in a Bright Zinc Plate.
Internal Shakeproof Washers are great where appearance warrants teeth to be hidden. They are also useful and work at their best with smaller screw heads.
External Shakeproof Washers work best with larger screw heads and provide maximum torsional resistance.
