Anyone know off hand what size thread the screws are for securing socket
plates to backboxes?

cheers

M3.5

Pretty common, but most easily found at electrical wholesalers. They
also sell rethreading taps with plastic handles which can be an
absolute godsend for some repair work.

M 3.5 mm

And isn't it Strange how M3, M4, M5 etc are common-as-muck sizes sold at
quid-or-two-gets-you-one-or-two-hundred prices, while the 3.5s having
more or less only this application are Specialist Items selling at 5 or
more times that price? (Well, economics of mass mfrg being what they
are, I s'pose it's not Strange. Presumably M3.5 was the closest in
diameter in metric sizes to the Imperial size previously used (4 BA?)
and it was considered more important to have only the backbox threads
and accessory screws change, leaving the holes in accessory plates
unchanged, than to use a widely-available size...)

Yehbut they're raised head screws which always seem to be more expensive
and rare. Ordinary 3.5mm pan or countersunk are easy enough to get.

25mm - 80mm in 5mm steps across the road from here.

I bet they dont do long versions of the slightly smaller headed screws that
came with the new sockets I bought! I have put some standard longer ones I
had in for the moment but the slightly larger head of the normal screws
stops some plugtops going right up to the socket face. Nothing seems to be
simple these days.

Sounds like you've bought some strange accessories. What make are they?

More likely strange screws. I got some "long" screws (50mm) from
Screwfix heads are just a tad larger than the counter bore in the
accessories. These screws also have a nasty slot/philips combination
head.

Ahh. Screwfix seem to specialise in sourcing their screws from strange
suppliers.

The only thing I can think of with non standard 3.5 mm screw heads were
some surface mounted phone sockets - the 3/4 size ones.

easily shrunk if you have an angle grinder and drill. Careful not to
damage the threads in the chuck though.

I thought about a grinding wheel but dont have one - never thought about
spinning the screw though, something to try )

Think they go under the name "Ultimate" or something - flat plate sockets
from B&Q

Apart from most screws of this type being plated. ;-)

Perhaps the correct screws are just plain countersunk if the plate is
shallow?

Curiously, BA sizes are in fact metric ! 4BA is 3.6mm diameter with a
slightly larger pitch than M3.5. I've found you can use M3.5 bolts in old
sockets, but not (obviously) the other way round. Perhaps this explains the
odd choice of size.

Yes, I've often surprised people by telling them that. I believe they
were a Swiss standard or soemthing originally.

They're plated for a reason. Durability and looks. Remove the plating
round the edge will probably show after a while.
