Sold in single units.
Frame mounting screw (bolt) for Seba inline skates such as 2014 model year and newer FRX, FR2, GTX and Marathon. This one mounts the frames onto the bottom of the boots. Two of these are required per boot. If you are using the regular axle tool to remove the frame bolts, then this is the right replacement screw for your skates.
