Over Wire Measurements for M110 X 6


* 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 3.031 - 6.062 0.1193 - 0.2387
Ideal Wire Diameter 3.464 0.1364
Possible Wires
From Standard Sets		 * 3.175
* 3.464
* 4.042
* 4.619
* 5.196
* 5.774
 * 0.1283
* 0.1443
* 0.165
* 0.1777
* 0.1925
* 0.21

Once you know your wire diameter, you need to find out what is the premissable Measurement for your pitch diameter (Depending on the class). Use our Over Wire Calculator to find out!
