[Elecraft] understanding screw sizes

[Gilbert Cross]

         Regarding machine screw sizes, American Standard.
         Screw numbers start out at o which has an OD of .060 inch. Each successive number has .013 
inch added to it to arrive at its OD. Thus a number 1 screw has an OD of .073 inch, a number 2 screw 
has an OD of .086 inch, and so on . Hope I presented this well.....
