Strange choice of screws? Good quality, but maybe need to provide a suitable screwdriver for that particular head type… not that common. I bought a pack of six screwdrivers for £5, so you could give a free screwdriver of the right size and it would probably only cost you 20p. It wasn’t the cost of buying a screwdriver set that was annoying, it was the need to go out and get one just as you start trying to install the blinds.
