Choke coming loose

[stevec223]

I use rig gun grease... On the hinges and everywhere there is hi contact metal to metal ... On the choke tubes in the threads and up on the smooth areas... I finger ck the tightness on extended and flush tubes after every 25 shots or every round of trap-skeet... Dont overtighten or go without lube on your tubes... I have seen a few rusted in tubes on duck guns,, that went back to the factory for removal !!! Cheers...

Update: SUCCESS!!

I bought a bottle of Permatex Nickle anti-seize and applied it on the choke's thread of my Benelli Supersport and tightened it with the supplied choke wrench. Shot 5 rounds of trap today (125 shells) and the choke remained tight.

This one:


Its almost weird how applying lubricant on your threads can result in it not coming loose, I guess the think grease act like filler for the thread and allow them to be threaded together tightly.

Grease decreases the friction between the threads. With less friction between the contact surfaces of the threads it is possible to tighten the choke more for a given torque. There is more clamping force generated with bolts as well if the threads are lubricated for a given torque applied to tighten the bolt.
