So update:

I got my hands on some machine screws. Unfortunately the pitch of the threads was off. I went to a fastener store and although they had almost everything they said these screws would be next to impossible to source.

I tried the machine screws. Everything went great for the first little bit. I shortened them slightly to fit the hopup. It was during assembly that the head of the screw decided it no longer wanted to cooperate and sheered clean off, leaving me with a fucked up hop up.
