M EASURING W IRES

•

Recognized as the standard method of obtaining the pitch diameter of thread plug or setting plug gages. Wire sizes are nominal. Calibrated size will show on the label with matching constant. In all cases the calibrated wire diameter will be within .000020”, all three wires in each set having the same size within .000010” et having the
