I cant unscrew one end of my plugs?

The part that unscrews is stuck.

Is there anyway to loosen the threading or something?

I just bought them and I cant even put them in because of this.


um, no, dont put anything on them, just put on a pair of latex gloves. you will be suprised how easy it is once your grip is improved by the gloves.


pour a drop of kerosene / turpentine oil on the thread and leave it in sun for a while. Then unscrew and screw it for few times to let the thread get align with the nut or body.
