New Very Thin Tempered Spring Steel "Valving Discs" / Flat Shim Washers, 5/16" ID x .707" OD x .010" Thick, Part Number M100252J4.  Each bid quantity is for a Lot of One Hundred (100) Washers.  You may bid / buy any number of lots, up to the total quantity available above.

These were purchased from a freight reseller earlier this year, and they were brand new in the original bulk factory bags.  We repackaged them in heavy Ziplok bags for resale.

These are NICE.  Absolutely flat, absolutely free of burrs, and absolutely uniform dimensions.  If you are needing to shim a 5/16" shaft in precise 1/100th inch increments, then these are the thing.  The bags say they are "valving discs" (whatever that is), and somebody spent major money manufacturing them.  You can probably bend one with your fingers, or you can cut your fingers, and one outcome is about as likely as the other.  The material is extremely tough and will attract a magnet.  They will start to discolor (rust) if exposed to water for several days.
