Size of Vert ASA bolt/screw?

[warbeak2099]

I want to get a screw for an automag vert asa but the ones online are $1. I find it somewhat ludicrous to pay $1 plus shipping for a screw. What size screw does the vert asa use? I want to pick one up at my local hardware store. Thanks all.

Used to say it on the page.

Thanks. Doesn't say it anymore on the online store.
