These are custom washers in 18-8 stainless steel, manufactured domestically at just under 4,000 pieces.  The lead time was approximately 6 weeks from order confirmation.  Inside width on the washer is .340" to .350" and the outside width is .466" to .500".  Plain 18-8 stainless steel material was used and our internal part number is WA-340466057-I.

Larger quantities of these custom flat 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.
