Over Wire Measurements for M36 X 1.5


* 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 0.758 - 1.516 0.0298 - 0.0597
Ideal Wire Diameter 0.866 0.0341
Possible Wires
From Standard Sets		 * 0.866
* 1.01
* 1.155
* 1.443

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!
