Drop through longboards require a special kind of button head hardware with gaskets between the mounting nuts. The typical counter sunk hardware just looks goofy on drop throughs doesn't it? Yeah, it does. It will also loosen easier and end up ruining both your board and your trucks becuase it doesn't properly align with the trucks and the nuts rub right up against the deck. Button head hardware aligns perfectly with the trucks and the washers provide separation between the deck and nuts. Starting with the right hardware is the most basic way to protect your set-up and prolong its life! Includes 8 1.5" Pan Head Bolts (Phillips), 8 Washer Rings, and 8 Mounting Nuts.
