What to do about a jumping thread?

[Oreoigloo2]

So I was screwing on my EHpro kayfun lite literally five minutes ago, to my Cana mod. As it starts getting tighter I twist some more to make sure it good on there. Then it kinda jumped on the threads.. Like it was locking up then "woop you can keep screwing!" I turned it once more and it started feeling like I was hitting the end... Then it happened again. My previous attempt to put the kayfun on my Nemesis showed it wasn't flush. One side had a gap, so does that mean my kayfun has terrible threading or what's going on?

So this isn't really a "fix" if the threads are damaged but when I'm screwing an atty on to a mod (or anything with threads) I'll go counter clockwise a little till you get the "feel" of threads all lined up and then proceed to tighten it down. This will ensure that nothing gets cross threaded & prevents damaging those threads

I have one of those the threading is not good to begin with. yoiu have to be very careful screwing it on. It was cheap and I knew what I was getting. I needed to be careful very careful when putting it on.
It from what you're describing the threads are stripped. when screwing anything down and it gets tight are hard turn before bottoming out stop back it off and inspect the threads closely. If you see any damage pitch it. You'll just ruin your mods forcing it on.
To see if it has stripped the threads on you mod try another tank,atty, whatever you have that went on your mods before see if they still fit like they did.
I've never heard of a 510 thread chaser if a some makes one they could make some money. I'd a bought one for my EHpro kayfun.

It's the intarweb, threads always jump....oh,.....wait, nm.

Have you cleaned your threads lately?

Simple - Over tightening strips threads. You did. Best to be careful from this point on, until it fails to hold anything.
There is a reason people recommend Snugging.

This, every time, for me. It occasionally happens with my Ehpro KFL near the end of the thread; it just wants to wiggle back and forth. Turns out, gunk in the threads from pocket/bag.

Just going around the threads with a tissue/shirt has worked every time so far.

I agree with cleaning your threads, but it still sounds like you might have stripped the threads on one end (preferably the cheaper end). Screw threads are not like riveting things in place, especially anything that goes on an e-cig. Don't expect things to fit so hard they will survive a war whether it be on a computer or a car. Finger tight is what you really need (or hand tight if we're talking about something that goes in with a screwdriver, just don't force it hoping it will stay put for years)... anything more is over-doing it and runs the risk of killing a thread.

Snuggling is always good

7mm x .5 metric tap and die for 510 threads.

Some people chase the threads on all Chinese atomizers before using them for the first time.

I have had that problem repeatedly (especially when I drop my Vamo or Sentinel). Easy fix. I ordered this airflow controller, Tank Airflow Controller . I tighten it down really well in my mod and then secure any tank or atty as I usually do. I have never had another jumped or crossed thread. It also protects the threads of the mod from dirt and repeated use.

Thanks for that!! I keep meaning to look into what the thread size is, but haven't really had a need yet... it has now been notated for future use!!

I was looking for that 510 thread nfo some time ago too. Thanks! Now I'm wondering if a bottom type tap is the best to use here.

Personally I replaced the connector before I used the case with a fatdaddy 14mm connector. A friend with a drill press or machine shop is recommended. It can be drilled/tapped by hand and will probably come out with a slight angle. A varitube 22mm connector looks like another nice option.

Yep... bottom tap to re-tap the mod, die to re-tap the atty...
