I have some ceramic disc quarter turn bath taps were the grub screw is between sizes. 2.5mm too slack. 3mm too tight. Is there a way around this so I can tighten the grub screw.

Just had a quick search you can possibly buy the grub screws separately if can get ones that fit
But not sure if will help as can't get the old grub screws out. The heads do pull up off the cartridge though

A tap (as in thread cutting), to suit the grub screw?
A tap head. That sits on the splines of the quarter turn ceramic disc cartridge. There is a grub screw that holds the head onto the tap.
Thanks it seems to be somewhere between 2.5mm and 3mmImperial sized hexes?

You may get it out with a T10 torx bit/driver.
1. A lot of the grub screws used in taps are rubbish. Too soft, so the correct size Allen key spins and makes the hole too big.
2. If you have a sharpening stone, rub down the end of an Allen key, 10 strokes at a time, at a shallow angle, until you can get it to fit. Preferably a tight fit where you have to tap the key with a hammer to get it in. Doesn't matter if it ends up a bit wedge shaped.
3. Replace with a decent quality grub screw and buy a new Allen key.

Thanks I think that's the problem poor quality grub screws
It's the grub screw that holds the tap head onto the splines. Cause I can't tighten properly the tap head is loose
