i just got some crail DH and put them on my strike and the first hill i went down the screws holding them down fell off. i just got some 10-24x1-1/4 round screws and put some nuts on the end. They are made out of zinc so i figured they would be strong enough. Am i missing something? are there some special scrrews that i need to get at a longboard shop?

edit: sorry this is supposed to be in the trucks section
