• Exact Torque Specifications: Each bolt is engineered to meet strict torque requirements, guaranteeing uniform clamping force across all cylinder head studs.
• Polished Finish: The polished threads reduce friction during installation, allowing for smoother tightening and minimizing the risk of cross‑threading.
• Compatibility: Designed specifically for Audi, Seat, Skoda, and Volkswagen engines that use the 351.900 bolt pattern, including models such as the A1, A3, A4, A5, Q2, Q3, Q5, and many others.
• Durability: The bolts are heat‑treated to maintain structural integrity even after repeated engine cycles.

Technical Specifications

Installation Guidelines

1. Preparation: Clean the cylinder head and bolt holes thoroughly. Inspect for any damage or wear.
2. Alignment: Place each bolt in its corresponding stud, ensuring proper alignment to avoid cross‑threading.
3. Tightening Sequence: Follow a star pattern when tightening bolts to distribute clamping force evenly.
4. Torque Application: Use a calibrated torque wrench and apply the specified torque values gradually. Recheck after completing the full sequence.
5. Final Inspection: Verify that all bolts are secure, with no signs of play or misalignment.

Maintenance Tips

• Inspect bolts periodically for signs of corrosion or wear, especially in high‑humidity environments.
• Avoid over‑tightening during future maintenance; use the same torque specifications to preserve bolt integrity.
• If a bolt shows any deformation, replace it immediately to prevent engine damage.
