@sillyyak, since you wrote, in another thread, that you're "... not scientific, hated maths and crap at fiddly mechanical things ...", I'm going to expand a bit on @Markw4mms comment, since you probably have no idea what the "center pin" is all about 
Basics on how vaping mechanics works
Battery, switch, coil, wick, e-juice. Battery supplies power to the coil, just like your mains do for lightbulbs. Switch turns it on and off, just like a wall switch (only you have to keep it pressed for it to be on). When you press the switch: Current passes through the coil and the coil gets hot. Just like the elements of an electric stove get hot when you turn them on. The wick, which has absorbed e-juice, passes through the coil. The e-juice gets hot, and, like the water in a pan atop the aforementioned electric stove burner, vaporizes.
The coil, switch and battery form an electrical circuit. You can kind of think of it like a pump and filter in a fish aquarium, which circulates water 'round and 'round thru tank and filter. When the circuit is "closed," or "completed," by pressing the switch: Electrical current runs around the circuit from the battery, thru the switch and the coil, and back to the battery.
This drawing illustrates it:
On an e-cigarette: The outside case of the battery and atomizer (aka: "tank") forms the "-" side of the circuit. The centre pin of the battery, the switch, and the centre pin of the tank/atomizer/coil forms the "+" side. The "center" part of the circuit connects to the "outer" part through the coil in the atomizer, just like the lightbulb/resistor in the diagram above.
Everything else, all the way up to high-tech mods, are simply refinements or expansions of the above principles.
A bit of physics for the curious (you can stop reading here if you like).
Yes, for those who are wondering: The diagram is correct: Current really does flow from "-" to "+".
Electrical current in a DC (Direct Current) circuit flows because of an imbalance of electrons on one side, compared to the other. In our case: The "-" side of the battery is the side with the excess electrons. So, when the circuit is completed, the excess electrons try to get to the side with a lack of them: The "+" side. This imbalance, in a battery, is created by a chemical reaction of one type or another.

That center pin (with the slot cut in it) on the Kanger coil heads is not adjustable.
You can screw it clockwise or counterclockwise, and it will not adjust in or out at all.

Oh it holds the center wire of the coil in place between the insulator and it self . also the insulator and the outer case . If you try and turn it you can snap the wire legs of the coils . It is also what you pull out to rebuild the coils .

If you have problems getting a good electrical connection between your EGO clearomizer and the little center pin in your EGO stick battery, here is what you need to do:
Get a real small flat-tip screwdriver (like those little plastic ones that come with many of the rebuildable atomizers you buy), and pry out the little center pin in your EGO battery. It don't take very much outward force to get it to move outward just enough to make a good contact with the end of the clearomizer's coil head (the part that has that little slot in it we were talking about).
Nothing to it.

Here you can see, how easy it is
