Can I use coated and uncoated screws to instull motherboard?

[tjsbod12]

I am installing a motherboard. They only gave me 4 coated black screws to install it and there are 9 holes in motherboard. The directions call for 6 screws to install it. Can I use non-coated screws from an old computer to install motherboard? Do I need to put screw in each of 9 holes? Will it matter if some are coated and some not?

Make sure that each standoff in the case matches a hole on the motherboard.
