WebbUnified screw threads have a 30° flank angle and are symmetrical. This is why they are commonly referred to as 60° threads. Pitch diameter is the diameter of a theoretical cylinder that passes through the threads in such a way that the distance between the thread crests and thread roots is equal. WebbFor a single thread screw, lead is equal to the pitch. For a double thread screw, lead is equal to twice the pitch, etc. Helix angle α is related to the lead and the mean radius r m by the equation: Equation 1 tan α = lead / ( 2 π r m) In some calculations we shall make use of the angle θ n measuring the slope of the thread profile in a ...
