3 mm Nylon Insert Lock Nuts, 4-Pack. These lock nuts use a nylon locking insert to resist loosening under vibration, while a zinc-plated steel body provides durability and corrosio n resistance. Designed for 3 mm bolts, they offer dependable locking performance in hobby projects and small machinery. The nylon insert creates friction to prevent self-loosening, and the zinc plating guards against rust; with four nuts in the pack, there's plenty for multiple builds or repairs. Show more
