KZ440 carb parts question

So some schmoog ghetto'd the carbs on the KZ440 I just bought. Among other things it looks like they lost most of the bowl screws. The part is listed as (220AA0408) SCREW-PAN-CROS. Does anyone know the dimensions of this screw? I was hoping to stop bye HomeDespot and see if I can pick some replacements up.

220AA0408

From that part number I'm pretty sure the last four digits indicate the size, so it's a 4mm x 8mm long screw. I don't know what the pitch is.

I hope you have the complete stock airbox for that bike. The KZ440 needs to have it correctly installed for it to run right. Other's have reported that it's very difficult to tune for pod filters.

Thanks ton's for the info. I do have the stock airbox, I just need to put a good filter in it. With any luck I'll have my carb rebuilt kits in the mail when I get home!
