Priced as a single 2" Panhead Bolt, and 3/8" Nut
Most set ups need 8
We would recommend 8. We have seen people not use 8. But we would use 8.
The 2" size is adequate for most longboard and skateboard set ups, and even has room left to facilitate a 3/8" riser or similar height of wedge/angle riser.
We like to use Panhead hardware when setting up a dropped through board, or at times when you won't be standing on top of the hardware and you are wanting to spread the force of the bolt out wider across the top not sink it into the board.
