zardos Posted July 8, 2012 Share Posted July 8, 2012 When I bought item no. 4 to blank a hole my parts supplier said it was a very old part number used, therefore likely to be imperial. I can pull it out and try and measure it for you if you want. Quote Link to comment Share on other sites More sharing options...
