17/19/21mm Colorful Wheel Nut Cover

J&W 17/19/21mm Colorful Wheel Nut Covers protect exposed wheel bolts from water, road salt, brake dust, mud, and other contaminants that can cause corrosion.

Each cover is injection molded from virgin HDPE (High-Density Polyethylene). The full-wrap design covers the wheel bolt completely, helping reduce exposure to moisture and dirt while keeping the bolt head clean.

Available in 17mm, 19mm, and 21mm sizes, these wheel nut covers fit many passenger cars, SUVs, pickup trucks, vans, and light commercial vehicles. Standard colors include black, red, blue, yellow, and silver. Custom Pantone or RAL colors, logo printing, and packaging are available for OEM and private-label orders.

Technical Specifications

Product Features

Virgin HDPE Material

J&W Colorful Wheel Nut Covers are injection molded from 100% virgin High-Density Polyethylene (HDPE). The material resists impact, UV exposure, road salt, brake dust, oils, and common automotive cleaning chemicals, making it suitable for long-term outdoor use.

The wheel nut covers operate in temperatures from -40°C to 80°C and maintain their shape during daily vehicle operation.

IP67-Rated Protection

Wheel bolts are exposed to water, mud, road salt, dust, and other contaminants that can lead to corrosion over time.

The enclosed cap design provides IP67-rated protection, helping reduce water and dust entering the wheel bolt area. This helps keep the bolt head clean and reduces exposure to moisture during daily driving.

Suitable for vehicles operating in coastal areas, snowy regions, humid climates, and off-road environments.

360° Full-Wrap Design

The wheel nut cover completely surrounds the wheel bolt head to reduce gaps where water, dust, and dirt can accumulate.

The interference-fit structure helps keep the cover in position during vehicle operation while allowing removal with a wheel nut cover extractor when wheel maintenance is required.

Comparison with Ordinary Plastic Wheel Nut Covers

Product Structure

J&W Colorful Wheel Nut Covers are injection molded from virgin HDPE and consist of four functional parts that work together to protect the wheel bolt and maintain a secure fit.

① Virgin HDPE Body

The outer body is manufactured from 100% virgin High-Density Polyethylene (HDPE). The material resists impact, UV exposure, road salt, brake dust, oils, and common automotive cleaning chemicals. It operates in temperatures from -40°C to 80°C and is suitable for long-term outdoor use.

② Inner Locking Structure

The inner locking structure is molded to fit the corresponding wheel bolt size and hold the cover in place after installation.

The cover can be removed using a wheel nut cover extractor during tire replacement or wheel maintenance.

③ 360° Full-Wrap Design

The cover surrounds the wheel bolt head to help reduce contact with water, mud, road salt, brake dust, and other road contaminants.

The enclosed structure also helps keep the bolt head clean during daily vehicle operation.

④ Injection-Molded Surface

Each wheel nut cover is manufactured by injection molding to provide consistent dimensions and wall thickness.

The smooth surface is easy to clean and is available in multiple standard colors or custom colors for OEM production.

Product Applications

J&W Colorful Wheel Nut Covers are used to protect exposed wheel bolts from water, road salt, mud, brake dust, and other road contaminants while providing a clean, uniform wheel appearance.

Size Guide – How to Choose the Correct Wheel Nut Cover

Selecting the correct wheel nut cover size is essential for proper installation and long-term performance. A cover that is too large may become loose during driving, while one that is too small cannot be installed correctly.

J&W Colorful Wheel Nut Covers are available in three standard sizes:

· 17mm

· 19mm

· 21mm

The size refers to the distance across the opposite flat sides of the wheel bolt or lug nut (Across Flats, AF), rather than the diameter of the threaded bolt.

Step 1 – Measure the Wheel Bolt

Use a digital caliper or an appropriately sized wrench to measure the hexagonal head of your wheel bolt.

Measure the distance across two opposite flat sides.

Choose the corresponding cover size:

For the most secure fit, always match the cover size exactly to the wheel bolt size.

Step 2 – Check Your Vehicle Specifications

If you are unable to measure the wheel bolt directly, refer to your vehicle owner's manual or wheel specifications.

Most manufacturers list the wheel bolt or lug nut hex size under the wheel or tire section.

Step 3 – Contact Our Technical Team

If you are unsure about compatibility, simply provide one of the following:

· Vehicle make

· Model

· Production year

· Wheel information

· Photos of the wheel bolts

Our technical team will recommend the correct size before you place your order.

Vehicle Compatibility Guide

The following table provides a general reference for commonly used wheel bolt sizes. Actual specifications may vary depending on vehicle model and production year.

Typical compatible brands include:

· Toyota

· Honda

· Nissan

· Mazda

· Mitsubishi

· Hyundai

· Kia

· Ford

· Chevrolet

· Jeep

· Volkswagen

· BMW

· Mercedes-Benz

· Audi

· Skoda

· Volvo

Please note: Compatibility depends on the wheel bolt hex size rather than the vehicle brand.

Installation Guide

Installing the wheel nut cover is quick and requires no special tools.

The entire installation process takes only a few minutes.

Step 1 – Clean the Wheel Bolt

Before installation, wipe away dirt, grease, moisture, or brake dust from the wheel bolt.

A clean surface helps ensure a secure fit.

Step 2 – Align the Cover

Place the wheel nut cover directly over the wheel bolt.

Ensure that the cover is properly aligned before applying pressure.

Step 3 – Press Firmly into Position

Press evenly using your hand until the cover snaps securely into place.

Do not strike the cover with a hammer or excessive force.

Once installed correctly, the cover should fit tightly without rattling.

Quality Inspection

Each production batch of J&W Colorful Wheel Nut Covers follows documented inspection procedures before shipment. Quality control covers raw materials, injection molding, dimensions, appearance, and packaging to help maintain consistency between production batches.

Raw Material Inspection

Virgin HDPE raw materials are inspected before production to verify material type, appearance, and batch consistency.

Injection Molding Inspection

During production, operators monitor injection molding parameters, including temperature, pressure, and cooling time.

Samples are checked throughout production to verify molding consistency and product dimensions.

Dimensional Inspection

Dimensions are measured using calibrated inspection tools.

Inspection items include:

· Inner diameter

· Outer diameter

· Wall thickness

· Locking structure dimensions

These measurements help verify compatibility with the specified wheel bolt size.

Appearance Inspection

Each production batch is visually inspected for:

· Surface finish

· Color consistency

· Flash and burrs

· Deformation

· Surface defects

Products that do not meet inspection requirements are removed before packaging.
