Adding extra gear

I have a poly Emotion and am going to add a couple of mesh gear bags to the inside of the cockpit. They are the ones designed for this kayak. According to the picture I saw, it appears I will drill 2 holes on to near where the splash guard hooks. There were no screws included, just the plastic hooks. Do I need anything special or can I go down to the hardware store and buy regular flat end screws or bolts and some nuts? Thank you for any and all words of advice.

You need a screw-mounted tie-down kit.
