The Yokomo ZC-N4FLTA M4 serrated flange nut is built to increase contact grip and reduce movement at threaded joints. The serrated face locks against mating surfaces to lower the chance of nuts backing off during hard landings and bashing.
This four-piece set suits several Yokomo layouts including B-YZ4SF, B-YZ4SF2-1 and MOR-010. Use them when replacing worn fasteners or upgrading suspension and body mounts to keep setups tighter on rough tracks.
