Does awning window crank #39-205 include fine thread screw and shoulder bolt washeor purchase seperately what would item # be.

Thanks for posting. The 39-205 is a casement window operator. Could you be referring to our 39-025 instead? If so, the 22-206 is the shoulder bolt washer. You can see it under "Related Items" on the 39-025 store page. It is sold separately.
