... If either the lug in the backbox (for the facia screw), or the screwhole for the cpc terminal in the back-box, is threaded, is there an acceptable way to rectify without changing the box?
cheers.

...thanks John, would they work on the cpc terminal (fixed to the back-box) too? If this tool is used, is a larger screw required?
The rethreader is 4mm same as original.
if it is a brass block that has been stripped, I do not know a good way to rethread it to the original size The hole will be too big and the tap will fall through it. Even if you could squeeze it oval the screw would not be reliable. but I suppose you could drill it out and rethread to next bigger size. An engineering supplier can sell you Taps in any size you like, and a tap wrench. They are very hard and brittle and can break if handled carelessly.
You can (could?) buy brass earth studs which are retained with a small screw and I suppose you might be able to fabricate a terminal screwed firmly to the box, but you would have to be very sure it would not come loose.
There comes a time when it is easier to knife out the box from the wall and fit a new one.

...understood. Thanks John.

He knows that... 
I must have meant 3.5mm
maybe I'll go and have a look at mine and see if it's got a number on the side
Johns been using the wrong one
No wonder he's been finding them hard work, and that afterwards the screws still won't do up...I must have meant 3.5mm
