17/19/21mm カラフルホイールナットカバー

The J&W Auto Part 17/19/21mm Colorful Wheel Nut Cover is primarily used to cover the exterior of wheel nuts or bolts, providing rust, corrosion, and dust protection, as well as decorative enhancement. Common sizes include 17mm, 19mm, and 21mm, suitable for most passenger cars and light commercial vehicles.
As a Chinese automotive wheel nut factory, we optimize the structure of our matching 17/19/21mm Colorful Wheel Nut Covers while producing wheel nuts and bolts. This ensures precise dimensional matching, preventing loosening and detachment.

Core Technological Advantages

1. High-Density HDPE Material
Made of high-density polyethylene (HDPE)
Excellent impact resistance
Resistant to temperature changes
Not easily brittle
Resistant to aging during long-term outdoor use
Compared to ordinary plastic materials, our 17/19/21mm Colorful Wheel Nut Covers exhibit greater stability in terms of UV resistance and oxidation resistance.
2. IP67 Protection Rating

This means that the wheel nuts will remain dry even in rain, high-pressure water washing, and muddy environments, reducing the risk of rust.
3. 360° Enveloping Structure
Full-coverage design
Closely fits wheel nuts
Prevents mud and sand from entering
Reduces salt spray corrosion
Especially suitable for vehicles in coastal areas or areas where de-icing salt is used in winter.
