E=Pitch diameter of thread. D=Basic major or outside diameter. W=Wire diameter. P=Thread pitch. M=E+Const. E=M-Const. Const.=3W-0.86603P(found in chart) The maximun and minimum pitch diameter(E) for each class of thread can be found in machinery hand book. Three wire method of checking pitch diameter of screw threads.

The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its major diameter and its pitch. ISO metric threads consist of symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other.

Used to gauge Metric sizes M4x0.7 through M12x1.75; Screw a fastener into the slot to determine the thread pitch and diameter/size; Measure nuts and washers
