The positive and negitive post are M1.6 x .35, but you might be able to salvage the holes that are in it by going to a M1.7 x .35. If the 1.7 doesn't work, then you'll have to drill and tap it for M2 x .4
Hah! Next time I have some money, I'll go get a tap and another bit for where the o-ring will go, plus some screws and o-rings. BTW, mine didn't come with a replacement o-ring for the fill hole, just a bunch of the small chimney ones. Any idea where I can get those?
If I'm not mistaking they are M2.0 - 0.4 You could get 100 of them for $5.00 here: Stainless Steel Machine Screw, Plain Finish, Pan Head, Phillips Drive, 4mm Length, M2-0.4 Threads (Pack of 100): Amazon.com: Industrial & Scientific
These are 4.0 mm long screws you could use to replace almost every bad (non stainless) screw that come in every fast tech RDA and RBA.
Don't feel bad. You stripped them not because you are sloppy, but because YiLoong drills their holes too wide and their threads are not full threads and super easy to strip.
I keep an endless supply of Tappers and Stainless Steel Screws for that reason. I re-thread them one size bigger when they strip.
All my Chinese Kayfuns have 1.7 mm Screws instead of 1.6 mm original, and most of my 2.0 mm Screws have been replaced with 2.5 mm by me:
Here is an example of me re-threading my Helios:
This is when I discovered that the Center Post is made out of chromed brass.

Would I need to re-thread anything to use these screws? (I've never done that before, so yeah)
Also, just looking at them they look a bit long... Will they still fit without me having to do anything?
Smaller deck yes, but its still raised. Also the most recent design does not allow you to vape all the liquid in the tank. Very different IMO

It depends what did you strip exactly... If you just stripped the threads on your screw, you might get away by just simply replacing it.
As far as the length is concerned, do not judge by the picture (they just use a random screw image). Those M1.6 mm screws and they are 4mm long. Work for Kayfun. If they are a little long for you, you could sand them down. But if you stripped the female threads of the deck, which I doubt because it is very hard to strip what is hardly there, then you will have to re-thread it a little bigger.
Ace seems to be the best choice for a national chain hardware store if you want Metric screws and the like. I found M5 set screws there for extended pins for my Nemesis top caps. Hobby shops, if they have anything, will most likely have just English sizes.Would that be a hobby shop or home depot?
