SW is the only place I can find reference to some category of Selected or Preferred for these types of Washers. ASME B18.21.1 have two series, Narrow (formerly "SAE washers") and Wide (formerly "USS Washers"). A quick check of the .094" washer shows that the Selected model matches the specification. But, I don't just want to assume.
Can someone tell me what is going on here?
The response from my VAR is:
Regarding the washers, they come from ANSI/ASME B18.22.1. The terms preferred and selected are used on tables that can be found in Machinery's Handbook. (Page 1512-1513 for the 26th edition.
