[bars] PL-259 dimensions?

[William Smith]

Hi All,

I seem to have PL-259 connectors that mate just fine, and others that allow the male barrel to screw all the way onto the female threads and bottom out without locking the teeth in place to prevent rotation (and fully clamp the mating faces together).

The older (Amphenol) ones I have seem to have a maximum threaded length of a little under 0.35 inches, while some of the newer ones bottom out at almost 0.40 inches.

I found this for the Amphenol spec:

but it doesn't really say how long the threads are, other than the panel receptacles, which are 1/2 inch or more....

Did someone change the spec, or is the usual chinese junk sourced on Amazon likely to make up specs and ship them out the door?
