Kyosho 1-N3043NA-S 5 pcs M3x4.3 Nylon Lock Nuts, Aluminium Finish  [KY-1-N3043NA-S]

Precision M3 nylon-insert locking nut

The Kyosho 1-N3043NA-S nut is supplied as a 5 pcs pack, sized M3x4.3 and fitted with a nylon locking insert beneath an aluminium silver surface. It is intended to fasten small components on radio-controlled models where improved resistance to thread loosening is required.

Fitting requires an M3 threaded bolt or shaft; position the nut on the mounting point and tighten to the suitable torque for the hardware in use. The nylon insert increases friction to counteract vibration-induced loosening, while the aluminium finish helps with general wear and mild corrosion resistance in hobby conditions.

Use these nuts for compact, vibration-resistant fastening tasks such as securing linkages, mounts, and small brackets. They are not suitable for mismatched thread sizes or non-modeling industrial uses.
