replacement screw for Siam Mods Carto Punch

[Dirgon]

I can't find anyone who has the information on what size a replacement screw should be. Went to Home Depot and looked through but couldn't find any loose self tappers.

I've sharpened mine twice but eventually it'll run out of metal so I'm trying to find some cheapy replacements, without dropping $15 on a new tap every couple months for no reason.

Anyone have any ideas? I know CoV sells a replacement for $6 but that's an outrageous price, besides the fact they're out of stock.

I would look to my local hardware store (not a big-box store), the old guy at my local store can find a replacement for any screw for really cheap.
