Dimensions of carb screws

[Headache]

So i done goofed and lost all four bolts in the grass. long story, not getting into it. so i looked up the parts and found model #98503-04014-00 (which is superceded by 98504-04014-00) - but i can't get the dimensions. I really just want to stop by my local hardware store and pick up some pan-head screws that are the same dimensions. Anyone have this info?
