Hi Dimebag
Page 4 of the standard gives the basic formula of N+1.35/P which in this case equals 2.558. On page 145 of the standard under the heading "Formulas for dimensions and tolerances in tables 5 to 63" item 4.1 dimension symbol Dri it gives the formula (N+1.35 / P)+.004 this equals 2.562. hope this helps
