Accusize EG06-1002 U.S. & Metric Thread Measuring Wire Sets

48 pieces 16 different sizes for all 60 threads.
Measures all threads from 3 to 48 threads per inch and all metric from 0.5mm to 6mm pitch.
3 wire method of measuring external threads.
Wires are fitted in a plastic case stamped with sizes.
Laminated chart complied from the U.S. Standard

Thread Measuring Wires and a micrometer are used to quickly and accurately measure pitch diameters of external threads
Comes with 4 thread measuring wire holders

Three wire method of checking pitch diameter of screw threads

M = Measurement over wires.
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 – 86603p (found in chart)

The maximum and minimum pitch diameter (E) for each class of thread can be found in machines’ handbook

Select the proper wire size for either the number of threads per inch (US) or thread pitch (Metric)Metric Measured pitch die (E) equals measurement over wires(M) minus decimal in “CONST” column Note: Basic P.D. equals basic major diameter plus decimal in “ADD” column minus decimal in “CONST” column
