The Yokomo YOKYX-13N set includes four thin 3mm nylon lock nuts made for locations on the YRX 12 chassis that require reduced nut height. The integrated nylon insert resists loosening due to vibration while maintaining a slim stack.
These nuts are ideal for wheel hub reassembly, tight suspension link connections, and any application with 3mm threads where standard lock nuts would intrude. The thin profile helps keep link geometry and clearances correct.
Advice for tightening: clear threads of debris, fit until the nylon engages, and avoid excess torque that may damage plastic parts or compress the insert. Replace nuts if locking force feels diminished.
