M30-3.50 Class 10.9 Nylon Insert Metric Lock Nut with Clear Zinc Cr3 Plating

DIN 985 Class 10.9 Nylon Insert Metric Lock Nut with Clear Zinc Cr3 Plating – Precision Locking for High-Strength Applications

The DIN 985 Class 10.9 Nylon Insert Lock Nut with Clear Zinc Cr3 Plating offers a smart balance of high tensile strength, secure vibration resistance, and corrosion protection—all in a compact, reliable fastening solution. Designed to meet DIN 985 specifications, this lock nut features a nylon insert collar that deforms elastically to grip the mating threads, preventing loosening under vibration or torque without damaging the threads.

Made from Class 10.9 medium carbon alloy steel, this nut is ideal for high-stress mechanical assemblies requiring superior tensile strength. The clear zinc Cr3 plating enhances resistance to rust and corrosion, making it suitable for both indoor and light outdoor applications. The plating provides a sleek, silver-toned finish while being environmentally safer than hexavalent alternatives.

This nut’s metric sizing and precision threading allow it to seamlessly integrate into European and international assemblies, including automotive components, industrial equipment, steel frameworks, and heavy machinery. Its prevailing torque design provides reusable locking capabilities while ensuring consistent performance over time.
