Cheaper here, but I assume you are in the UK.

 

I noticed Ricambi says Not available. Did you try used from Ferrparts? I bought a few things from them, but it has been several years.

 

The £7.75 ones are aftermarket, probably standard black screws in suitable length (I assume they are M6). Here are examples of 16 mm long screws from a US website, they also have other lengths:

Maranello Classics has them but for the similar price as Eurospares.

If you just was black button head screws or Allen head, hardware store will usually have them. But don't confuse black zinc plated for black oxidized. Black oxide will rust.

Closest I could find are these, but hex head.
