Shorty's Allen Hardware
Can't go wrong with Shorty's Allen Hardware. You get a set of 8. Black bolts and silver nuts. Shorty's bolts have smaller heads for less stress on your board and less weight. The top half isn't threaded to make sure they're even stronger. Includes allen key and a sticker, fo sho.
Note: 7/8 hardware is too short to work with riser pads.
