5. Installation
Proper installation is crucial for the safety and performance of your vehicle. It is recommended that installation be performed by a qualified technician. Refer to your vehicle's service manual for specific torque specifications and procedures.
- Preparation: Ensure the mating surfaces are clean and free from debris, rust, or old threadlocker.
- Positioning: Carefully align the bolt with the intended mounting hole. Refer to the exploded diagram (Figure 5.1) for typical placement.
- Initial Fastening: Hand-tighten the bolt to ensure proper thread engagement and prevent cross-threading.
- Torque Application: Using a calibrated torque wrench, tighten the bolt to the manufacturer's specified torque value. Over-tightening can damage the bolt or component, while under-tightening can lead to loosening and failure. The red coating on the threads indicates a pre-applied threadlocker, which aids in securing the bolt.
- Final Check: Verify that the bolt is securely fastened and that all associated components are correctly aligned and stable.

6. Application
The Mopar 06512205AA bolt is designed for specific fastening points within a vehicle's engine or chassis components. Its alloy steel construction and precise threading make it suitable for applications requiring high strength and resistance to vibration. Always ensure this bolt is used in the exact location specified by the vehicle manufacturer to maintain structural integrity and safety.
7. Care and Handling
To ensure the integrity and performance of the bolt:
- Store in a dry environment to prevent corrosion.
- Avoid dropping or impacting the bolt, which could damage threads or the head.
- Do not reuse bolts that show signs of stretching, thread damage, or head deformation. Many automotive bolts are designed for single use.
- If the pre-applied threadlocker (red coating) is damaged or removed, apply an appropriate threadlocking compound as specified by the vehicle manufacturer before installation.

8. Common Issues and Troubleshooting
While this is a simple component, issues can arise from improper handling or application:
- Bolt Does Not Thread:
- Ensure the correct bolt (M12x1.75) is being used for the application.
- Check for cross-threading. If resistance is met, back out the bolt and re-align.
- Inspect threads on both the bolt and the receiving component for damage.
- Bolt Loosens After Installation:
- Verify that the bolt was torqued to the vehicle manufacturer's specifications.
- Ensure the pre-applied threadlocker was intact or an appropriate threadlocking compound was used.
- Inspect for excessive vibration in the assembly.
- Head Damage During Tightening:
- Ensure the correct 6-lobe socket or tool is used.
- Avoid using worn or ill-fitting tools.
- Do not exceed specified torque values.
