Type: C - Spherical seat washer

Standard Sheet DIN 6319 Print This Page ISO Fundamental Tolerances

Product description

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

Type G dished washers with enlarged outer diameter are mainly used on elongated holes.

When utilizing DIN 6330 type B fixture nuts with spherical end, use either the type D or type G spherical dished washers. The type C spherical seat washer is not required.
