my faucet handle has 18 gears or spline, how to get a 20 spline to fit?

replace the faucet handle or buy new set.

Do these fit a howdens lamona hi-tec qt tap3407 kitchen tap?

I ended up having to replace the whole tap top as the Howdens taps were an awkward size, would have been £24 for the cartridges so got while tap top for £12.

Please do you know whether these are compatible with the perrin &rowe callisto tcb118 wall mounted basin mixer ? thank you x

I don't know they're fairly standard basin tap valves for those with separate hot and cold valves on the mixer. However, these were the worst engineered pieces of hardware I have ever purchased. The original pair were cracked and badly filed. The replacements were marginally better. Avoid. Get more expensive ones from a reputable store or replace your tap with a lever mixer with a ceramic cartridge.

Wiill they fita Lamona kitchen tap?

should do depending on the tap. there are many different taps !
