For example, 1/2-13+.010".

> Hi All,
> While at the Zolfo Show a week or so ago I picked up a nice old tap and 
> die set made by Wiley & Russell (Greenfield, Mass.) (It's got to be rather 
> old because the 1/2 " die indicated 12 threads per inch!) The set goes 
> from 1/4" to 3/4" and each die (while removable) has it's own handle! The 
> set is in a nice old wooden box measuring  37 1/4" X 10 3/4" X 3".
> Now my question. Each die has 1/32 stamped (or perhaps engraved) into it. 
> What does this 1/32 stand for/mean? Any help on this will be appreciated!
