The 4 locknuts included are enough to outfit 2 trucks. These axle nuts are the standard size and will fit on all skateboard/longboard trucks that have 8mm axles (virtually every truck has the standard 8mm axle size). The thread size for these axle nuts is 5/16". Produced with top quality materials. Having brand new lock nuts will keep your wheels from falling off. The more you replace your wheels and bearings, the more the axle nuts wear out and lose their ability to stay tight. These fresh new nuts will keep you locked up!. 4 Axle Nuts - enough for a complete skateboard.
