Fixaball BA Imperial Internal Shakeproof Washers Zinc BZP DIN6798J

For BA and imperial fastenings, these Fixaball internal shakeproof washers feature overlapping serrated teeth and are supplied in a range of diameters. Manufactured to DIN 6798J, they are available in zinc BZP or self colour finishes depending on size.

The internal teeth leave a rounded outer edge, while the overlapping tooth pattern creates a deeper indent when tightened for a more secure lock. These washers are suited to permanent joints and can also help insulate steel screws from aluminium surfaces to reduce galvanic corrosion. Zinc coated and plain steel versions are intended for indoor use.
