Custom Steel Spring Washers - Black Oxide Finish

These custom steel spring washers were manufactured using high carbon steel material heat treated to 38-45 HRC with black oxide finish.  When flat, the inside diameter measures .126" and the outside diameter is at .245".  The thickness is set to .004" +/- .005" with our production parts mostly measuring around .007" in thickness.  In it's final shape the OD across the bent sides is at .231" +/- .005".  Production is typically done at 150,000 pieces at a time, which is the MOQ due to the tiny nature of this spring washer.

Large bulk quantities of these custom made spring washers would be best supplied on a 12 month blanket purchase order basis.  The Blanket Order concept allows the customer to access the large quantity cost savings without paying upfront for the entire large quantity order. Instead we take on the burden of carrying the bulk inventory and only release the parts as needed, or often on a pre-scheduled basis provided by the customer.
