Our M8 Decorative Wheel Hub Bolts are engineered to provide a sleek, customized aesthetic upgrade for your vehicle's wheels without compromising on strength or function. Manufactured from high-quality stainless steel and finished with a deep, durable black electroplating, these bolts offer exceptional corrosion resistance and a sharp, uniform appearance. The precise hexagonal head ensures easy installation and a clean, professional look that enhances the overall style of your alloy wheels.

Primary Uses & Applications:

These bolts are specifically designed for aesthetic enhancement and secure fastening in automotive applications:
*   **Primary Use:** Replacing standard factory wheel bolts on alloy wheels for a customized, high-end aesthetic look.
*   **Vehicle Customization:** Ideal for car enthusiasts looking to add a personal touch and create a cohesive color scheme (e.g., black bolts on black wheels).
*   **Show Cars & Restorations:** Provides a clean, detailed finish for vehicles where appearance is paramount.
*   **Compatibility:** Designed to fit most standard passenger vehicles where M8x1.25 thread pitch is specified. *Always verify thread pitch and length compatibility with your vehicle's hub and wheel specifications before purchase and installation.*

How to Use: 

**Warning:** Incorrect installation can lead to wheel detachment. Ensure you have the correct specifications and proper tools. If unsure, consult a professional mechanic.
1.  **Vehicle Preparation:** Park the vehicle on a flat, level surface. Apply the parking brake and secure the vehicle with wheel chocks. Loosen the lug nuts/bolts on the target wheel slightly before lifting the vehicle.
2.  **Lifting:** Use a jack to lift the vehicle until the wheel is clear of the ground. Support the vehicle securely on a jack stand.
3.  **Removal:** Fully remove the existing OEM lug nuts/bolts and carefully remove the wheel.
4.  **Cleaning:** Clean the wheel hub mounting surface and the new bolt threads to remove any dirt or debris.
5.  **Installation:** Align the wheel and hand-thread the new decorative black bolt into the hub thread to avoid cross-threading.
6.  **Tightening:** Using a calibrated torque wrench and the correct 13mm socket, tighten the bolts in a star or criss-cross pattern in stages. Do not overtighten.
7.  **Final Torque:** Gradually tighten to the vehicle manufacturer's specified torque setting for wheel bolts (typically between 90-120 ft-lbs / 120-160 Nm for most passenger cars - **ALWAYS CONSULT YOUR VEHICLE'S MANUAL**). Do not use an impact wrench for final tightening.
8.  **Re-check:** After driving a short distance (~50 km), re-check the torque on all bolts.
