Grade C Nylon Insert Locknut, NE Style, Yellow Zinc Cr6 – Inch Sizes: High-Strength Locking with Vibrant Corrosion Protection

The Grade C NE nylon insert locknut with Yellow Zinc Cr6 plating is the top choice for high-strength, vibration-resistant fastening where durability and corrosion resistance are equally critical. Built for inch-size threaded applications, this locknut is forged from Grade C hardened steel, making it ideal for heavy-duty assemblies in construction equipment, transportation systems, agricultural machinery, and industrial fabrication.

The NE style indicates a full-height, heavy-pattern design that enhances torque retention and overall holding strength. A nylon insert embedded near the top of the nut provides prevailing torque, creating a secure, self-locking mechanism that resists loosening due to vibration, thermal cycling, or shock loads—without damaging bolt threads.

What sets this locknut apart is its Yellow Zinc Cr6 finish. The bright gold appearance isn’t just for looks—it provides robust corrosion resistance, especially in environments exposed to moisture, grease, and fluctuating temperatures. The hexavalent chromium (Cr6) coating delivers extended durability and makes fastener inspection easy in complex assemblies thanks to its high visibility.
