An SO/PL239 is pushed on, not twisted, until the face of the male is against the ridged edge of the female, then the outer shell is threaded on and tightened. The center pin never turns nor has any torque applied.
I cannot picture how you could "spin" the CENTER conductor. That would require twisting the coax attached to the male half. Ron AC7AC -----Original Message----- I've found the same problem with two batches of Teflon insulated, single hole mount SO-239 connectors manufactured in China and purchased from RF Connection. The center pin spins within the Teflon bushing and unless the user is extremely careful when connecting a PL-259, the wire connected to the center conductor will break off. I returned one batch and received a second batch that were supposed to be correct and found the same problem. I rejected those as well. I agree that a connector with this problem should not be used - too great a risk of damage to the internal wiring.
