NF E25-511 Stainless Steel Serrated Conical Washers

Choose the form as well as the nominal size. The supplier lists separate item references for narrow, medium and wide versions, so the same M size does not identify a single washer.

Product photos show the wide form. Narrow and medium forms are listed separately in the specification table; select the required form and item reference when requesting a quotation.

Product overview

  • Material listed by the supplier: 304 stainless steel.
  • Forms: narrow, medium and wide, retained as separate groups.
  • Supplier catalogue reference: NFE25-511.
  • Marking: unmarked for every listed reference.

The supplier lists narrow and wide forms from M3 to M12, and the medium form from M3 to M20. The M value is the catalogue nominal fastener size; it is not a measured bore diameter. Confirm the inside diameter, outside diameter, thickness and free height against the required drawing.
