2 Kingpin Nuts - enough for a complete skateboard. Having brand new lock nuts will keep your trucks from falling apart. The more you tighten and loosen your trucks, the more the kingping nuts wear out and lose their ability to stay tight. These fresh new nuts will keep you locked up! Produced with top quality materials. These kingpin nuts are the standard size and will fit on most skateboard/longboard trucks that have standard kingpins. The thread size for these kingpin nuts is 3/8" (standard). The 2 locknuts included are enough to outfit 2 trucks.
