The Skate Future 3/8" Base Screw is tested, approved and used by our team. Its 25mm size is ideal for skateboarding, without being too big in relation to the base of the truck. The nut with pressure is 3/8 in. 8", compatible with virtually all skateboard wrenches. It also uses quality raw material, which allows several changes without damaging the screws or wasting the nut. It even comes in a practical Ziplock packaging that can be reused for whatever you want
