I would remove one of the hood scoop screws and measure it with a metric thread pitch gage. Or take it to Ace hardware and match the length and pitch.
As Morris pointed out Mcmaster is the best. But they don't have Metric/Button head/Allen/Stainless screws. (Panhead,Flat, large area, etc...Yes)
Albany does sell what you need though as Indy mentioned.
