Over Wire Measurements for M130 X 3


* 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

mm Inch
Permissible Wire Diameter Range 1.516 - 3.031 0.0597 - 0.1193
Ideal Wire Diameter 1.732 0.0682
Possible Wires
From Standard Sets		 * 1.732
* 2.021
* 2.309
* 2.598
