Product Description
A2 Stainless Steel Conical Seat Washers – DIN 6319 Type D
These A2 stainless steel conical seat washers conform to DIN 6319 Type D and are designed for use with matching DIN 6319 Type C spherical washers. Together, the two components accommodate small angular differences between a bolt or stud and its supporting surface, helping the fastener seat correctly in clamping assemblies.
The matched washer and seat combination allows approximately 3° of angular adjustment in any direction. Available nominal sizes are M6, M8, M10 and M12.

Typical Applications
Used in machine fixtures, jigs, maintenance equipment and bolted clamping arrangements where small angular differences need to be accommodated at the fastener seating surface.
Installation
Position the flat underside of the Type D seat against a suitable supporting surface, with the conical recess facing the matching Type C washer. Fit the convex spherical face of the Type C washer into the recess, leaving its flat face against the nut or bolt head. Ensure both components are the same nominal size and correctly seated before tightening.
