Drew and all,

I beg to differ, unless you meant something different than I read.
The threads on a PL-259 connector are the only thing that connects the coax shield to the SO-239 jack.

That is why hand tightening of PL-259 connectors is not sufficient. Use pliers to snug them up just a bit more to assure a good connection.

BNC and N connectors do not have a similar requirement. They will make positive contact without being tightened.

Note that there is no electrical connection through the threads on the plug body and the threads on the shell; these threads are merely a stop to keep the shell from sliding down the cable when not connected to the SO-239 on the equipment.
