I have removed a twin socket from its back box.
When I came to fit the socket back in, I realised that one of the threaded lugs
for securing the socket to the box has in the past has had the thread slightly
damaged such that bolt won't really tighten up.
It looks OK as the good bold tightens up well and pulls the socket back to the
plaster. But it's not perfect.
Is there a trick for "tightening" the thread such that the bolt will hold in it
securely and tighten up,
I wondered about epoxy putty or similar to put in the lug hole (ear??) and
effectively make a new thread.
Any ideas please?
