Insert Lock Nuts, Nylon, 5mm (4) (DUB2175)

These nylon insert lock nuts fit 5mm threaded fasteners and come in a convenient four-pack, providing a secure, vibration-resistant connection for lightweight assemblies.

The built-in nylon insert creates a locking action as the nut is tightened, helping prevent loosening when parts are exposed to vibration. The zinc-plated finish adds durability and corrosion resistance, making these lock nuts suitable for hobby projects, RC builds, and other small-scale applications where reliable fasteners are needed.
