#6-32 UNC NM N2 (A) Nyloc Insert Locknuts Clear Zinc Cr3 Plating

Low Carbon Grade N2 (A) Nylon Insert Locknuts with Clear Zinc Cr3 – Versatile, Vibration-Resistant Locking Solutions

Low Carbon Grade N2 (A) Nylon Insert Locknuts with Clear Zinc Cr3 plating are trusted fastening solutions across industries requiring secure, vibration-resistant connections in low to medium-strength applications. Designed for performance and affordability, these locknuts utilize a pre-installed nylon insert that grips the bolt threads to deliver prevailing torque and resist loosening under vibration or dynamic loads.

Manufactured from low carbon steel, these Grade N2 (A) nuts meet general-purpose strength requirements and offer excellent machinability. The clear zinc Cr3 plating (trivalent chromium) adds a protective layer against corrosion while offering a bright, clean finish. This makes them ideal for indoor and light-duty outdoor applications.
