I had to take a switch off the wall and when I came to replace it the screw will no longer bite, it appears the thread in yellow bit shown in the picture has warn down. If anyone could let me know what they are called so I can replace it I will be very thankful.
Cheers

No Idea.

If all else fails drill and tap the back box and use longer screws cut to suit.

No idea what they're called, I doubt you'll find then for sale as a part on their own.

Find yourself a 5mm rawplug and trim it with sidecutters so it can be shoved in the oversized hole. If necessary sharpen the screw slightly to help it make a new thread. Bob will immediately be your uncle.

Cannabilise another metal backbox by taking out the adjustable screwplate and tuck it behind the 2 lugs on your back box!

I have come across these a while back , they are imperial fittings and will take the slightly larger imperial screws , there should have been imperial screws already in use , if not get some , they are slightly larger diameter , not sure where you get them , I always save mine up when I remove old fittings,,

You'll probably get imperial or whitworth screws from RS Components.

Agreed.

But I've never seen yellow plastic bit before - just black ones.

DOUGH!! Several days and an eager labourers broom passed before I needed to refix it.
Lesson learnt!

3/16" Whitworth or 2 B.A. maybe? Both are close to 5mm.

I've found it to be so far, then again I'm not grumpy, old or bald. Even if all three are approaching me far faster than I would like.
