PL259 Thread standard
The TPI between the two standards (American and metric) - in this
case - are very close resulting in very little thread stock being removed. In fact the TPI's are not that close 24tpi for American (1.06mm pitch) and 1.5mm pitch for Metric fine. Jeff |

(5/8 - 24 is not an ordinary fine thread either.) 73, Gene W4SZ |
