Over Wire Measurements for M60


* OverWire is a measuring method to obatin the pitch diameter of threads. It is mostly used when a manufacturer does not have a Go/Nogo gauge for a thread. You can learn more about it here

Permissible Wire Diameter Range 2.779 - 5.557 0.1094 - 0.2188
Ideal Wire Diameter 3.175 0.125
Possible Wires
From Standard Sets		 * 2.887
* 3.175
* 3.464
* 4.042
* 4.619
