Holding the curtain rail to the bracket:Lost grub screw - what size?

[notting]

Hi All,

We've lost the hex grub screw that is used for securing the curtain rail to the bracket.

Does anyone know if there is a standard thread/size that is used for curtain rails?

Thanks,
N

I think your best bet is to buy one of those assorted packs you can get online or in places like Homebase -- nobody will sell one individually.

I've just measured the screw and it's 4mm in diameter and 13mm in length.

Is there any way of telling if it is metric or imperial?

Last thing I want to do I buy a million metric screws, none of which fit. I've done that too many times in my life!!

I've lost practically all my grub screws over the years. Doesn’t really affect anything.

Except in this case when a child pulls on the curtain, the pole falls off.

Ah, right, my children are in their thirties and don’t live at home any more.

Or if you have a heavy-handed other half!

You can use a screw with same thread , doesn’t have to be grub screw.Usually metric .
