Dimension of 8UN-series Nuts & Washers for large flanges, ANSI dimensional standards

Hi Folks,

Can anyone please provide [U]dimensional[/U] standards for large diameter studbolt Nuts & Washers (to suit for example 2", 2¼" or 3" etc studbolts as used with large diameter thick flanges)??

Studbolts over 1" in diameter are typically "8UN-series", i.e. 8tpi UNC threadform to ASME B 1.1 with tolerances to ASME B1.2; Mechanical properties are to ASTM A193, while mech properties of nuts are to ASTM A194.

I believe that the ASME/ANSI Heavy Hex Nut standard is ASME B 18.2.2
and washers to suit are to ASME B18.22.1

it is these last two that I'm looking for ...

Thanks
