Nominal Diameter: D = d
Pitch: P
D1 = d2 - 2 · (H/2 - H/4) = d - 2·H1 = d - 1,082532·P
Diámetro de francos: D2 = d2 = d - 3/4 · H = d - 0,649519 · P
Core Diameter: d3 = d2 - 2 · (H/2 - H/6) = d - 1,226869 · P
Core Diameter: d3 = d1 - H/6 (up to DIN ISO 724)
H = (raiz(3)/2)·P = 0,866025 · P
H1 = (D - D1)/2 = 5/8 · H = 0,541266·P
Thread depth: h3 = (d - d3)/2 = 17/24 · H = 0,613435·P
Thread radius: R = H/6 = 0,144338 · P
