When doing 2nd fix eletrics it is found that one of the screw hole
lugs on one of the new metal back boxes has no thread so only one
screw instead of two can be used to secure double socket faceplate
to the new back box. Are there any better solutions than digging
out the new metal back box, fitting new box and redoing plaster
around the replacement box? Regards Stephen.

Once I couldnt use an M3.5 tap to sort it, I forget why, and just
used a woodscrew of exactly the right diameter. The screwheads dont
look quite right though.

That would be a bodge I couldn't live with.
