Sinotruk HOWO Hexagon Flange Bolt 082V03216-0157 – High-Strength M14x1.5 for Engine & Chassis

Product Description: Sinotruk HOWO Hexagon Flange Bolt (Part No. 082V03216-0157)

Ensure maximum clamping force and vibration resistance with this high-strength Hexagon Flange Bolt (082V03216-0157) — an OEM-equivalent fastener designed specifically for Sinotruk HOWO A7, T5G, T7H, Sitrak C7H/C9H, and other CNHTC heavy-duty trucks.

This all-in-one flange bolt integrates a washer-faced collar beneath the head to prevent loosening under constant road vibrations, making it ideal for critical engine, transmission, suspension, and chassis mounting applications.

Manufactured from quenched and tempered alloy steel (Grade 10.9) , this bolt delivers superior tensile strength, fatigue resistance, and durability in extreme operating conditions. The precision-threaded M14x1.5 design ensures smooth engagement and secure fitment without cross-threading.

Common installation locations include:

• Cylinder head covers

• Gearbox mounting brackets

• Axle assemblies

• Radiator support frames

• Cab mounting points

Each bolt is rigorously tested for dimensional accuracy, torque performance, and anti-corrosion protection — meeting CNHTC quality standards and ISO9001 certification. Whether you're repairing a single component or maintaining a full fleet, this genuine-specification flange bolt provides reliable, long-lasting performance and peace of mind.

How to Install Flange Bolt 082V03216-0157:

1. Clean Threads: Remove dirt, rust, or old thread locker from both bolt and mating hole.

2. Inspect Hole Condition: Ensure no stripped or deformed threads in tapped holes; re-tap if necessary.

3. Apply Proper Lubrication: Use light oil or assembly paste on threads — never use grease on high-torque structural bolts unless specified.

4. Hand-Tighten First: Start by hand to avoid cross-threading.

5. Use Correct Tool: Apply a 19mm socket wrench or impact gun with calibrated torque setting.

 6. Torque Gradually: Tighten in stages (e.g., 50% → 75% → 100%) to ensure even load distribution. ◦ Final Torque: 180–200 Nm

7. Check Alignment: Ensure flange seats flat against surface; no tilting or gap.

8. Avoid Reuse: Do not reuse stretch bolts or those showing signs of plastic deformation.

9. Mark After Installation: Use paint marker to indicate completion and check for movement during maintenance.

10. Follow Sequence: When installing multiple bolts (e.g., cover plates), tighten in crisscross pattern.
