Help...need replacement screw

[Duane Clark]

I purchased an aquamax media reactor from Marine depot and had a stupid accident while setting up a chaeto reactor. I broke off one of the screws that holds the top plate in place. I don't know if it will leak or not but need to replace this screw. Marine depot is closed so anyone know which screw I need to replace this?

home depot and lowes have some nylon screws in the hardware section in the specialty parts drawers ,,worth a try if they are in your area
