This Kyosho 1-N3043NA-S nut is an RC-scale accessory supplied as a 5 pcs pack, specified as M3x4.3 with a nylon insert and an aluminium silver exterior. It is intended for securing small components on model vehicles and aircraft where a compact locking nut reduces the chance of thread loosening during use.
Installation is straightforward: pair the nut with an M3 threaded bolt or shaft, seat it against the mounting surface, and tighten to the appropriate hand or equipment torque for your model's hardware. The nylon element provides friction to resist vibration-induced backing off, while the aluminium finish helps with durability and corrosion resistance in typical hobby conditions.
Use this part where a low-profile, vibration-resistant fastening solution is required on scale RC assemblies, such as linkages, brackets, or accessory mounts. Do not assume compatibility with unrelated hardware sizes or non-RC applications.
