This is a formula for calculating the effective diameter of screws with a 55-degree thread angle, such as parallel threads used in piping.
E = M - 3.16568d + 0.960491P
M
mm
dm
mm
P
mm
Effective diameter of a screw mm
E = Effective diameter of the screw
M = Outer diameter of the screw, including the three pins
dm = Optimal diameter of the three pins
P = Screw pitch = 25.4 ÷ number of threads
