Information

Spherical washers and dished washers DIN 6319 are used for clamping on non-parallel surfaces.

Thanks to the material used, the spherical washers and dished washers are generally suited for aggressive environmental conditions.

The dished washers type G with enlarged outside diameter are mainly used on elongated holes.

When utilizing hexagon nuts with spherical seating DIN 6330 type B the spherical washer is redundant.
