Herman's advice is probably the best - if Classe has true cusomer support (many/most companies won't deal with screws).
If that fails, google "machine screws", or simply "screws". then you can spend hours trying fo find the exact one you're looking for, only to find out you need to spend $75 to buy a crate of them. good luck . . .
I'll be surprised if you find the exact replacement at the hardware store, unless it's a very standard size/type/material.
