The outer casings on these pots seem to be stainless steel and soldering to the casing can be somewhat difficult.
My question is, instead of soldering to the back of the pot would I be able to get a good ground/earth connection by wrapping the ground wire around the thread near the shaft and then screwing it tight during insulation?
Any advice would be greatly appreciated.

No, it needs to be soldered. Even if you were able to get a connection, the problem with wrapping the wire around the pot is that the wire will move if it is not soldered into place. Since the casing of this pot is so difficult to solder to, we recommend running a wire or component to a ground lug elsewhere in the guitar or circuit.
Apparently, the other responder to your question didn't read it very carefully! If, in fact, you wrap the ground around the shaft threads, and screw it down tightly, you should achieve an acceptable ground (of course, I'm sure you will check this before you completely re-assemble the guitar!). And, unless you have gremlins in your control cavity, or completely abuse the instrument regularly, that wire should stay right where you left it until you dis-assemble the guitar again!
