I know they charged me too much for those screws, specially because I saw the prices online, and some places in England sell them for just a few cents, and here in the US for les tan $3.
But I do not order anything from the internet and I needed my guitar the next day.

I am not sure if the other screws fit the nut blocks, I think those are strap locks.
These are the ones I am talking about.

I paid too much regardless.
