At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 6319C/D. Spherical washers and conical seats used as a matched pair to compensate for angular misalignment (approx 3-4 deg) between a bolt and a non-parallel bearing face. Form C is the convex spherical washer (male); Form D is the concave conical seat (female). Form G/K are the taller/dished variants. Sized to bolt clearance holes M6-M20.
