CE4s not fitting my infernos

[dgm76513]

I go to screw them on, and after about a quarter turn they become stiff to turn, and they rock from side to side. Upon screwing them down further, they become stiffer and still rock. It seems as though they're threaded differently. Any chances these could not be 510 threaded CE4 clearos?

I have two CE4 clearos, and have tried them on three different inferno batteries all with the same issue. Everything else I have threads into them nicely.

Ah nevermind. I needed a 510 to ego adapter. Mods you can delete this thread if you want.

Great post as I am sure some folks don't realize you need the adapter for these.
