#4 countersunk flush SS washers-source needed

lwfussell · #1 10-31-2006, 03:08 PM

Does anyone know of a source for Stainless Steel Countersunk Flush Tinnerman (finish) Washers the part Number I believe is NAS1169-4C. For the past week I have searched the normal Aircraft sites and a number of fastener sites including Tinnerman. Only needing a box of 100 has generated zero response from the Fastener guys and Air Craft Spruce no longer carries them. Any help in locating a source would be greatly appreciated. As an alternative if I could find a thin say .010-.012 SS washer about 1/2inch in diameter with a #4 hole I could try to dimple them with a squeezer.

I am using #4 countersunk screws to attach the wingtips and don?t like what it does to the paint. Any other alternatives would also be appreciated.

Aircraft Spruce link shows only #6, #8, and #10, no #4.
