Although they can be more expensive than other screws that can easily be bought in packages, these screws have unique properties that set them apart do pocket holes. I bought a pack of screws from Daiso (there's a $2 store for everything) that looked like this, thinking they could be used for pocket screws. Instead he got stuck. So I used those Kreg screws again. My advice is to go to the Kreg website and find the right size and type before you buy.
