Over Wire Measurements for M52 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!
