Genuine Sinotruk HOWO Hexagon Nut with Shoulder (Flange Nut) - VG1200040034

In a heavy-duty diesel engine, the smallest components often carry the heaviest loads. The VG1200040034 Shoulder Nut (also known as a flange nut) is a specialized fastener used primarily across the Sinotruk WD615 and D12 engine platforms.

The "shoulder" design is not just for aesthetics; it acts as an integrated washer to distribute clamping force over a wider surface area. This is vital for preventing loosening caused by the intense harmonic vibrations of a 12-liter engine. Using a standard nut instead of the OEM VG1200040034 can lead to uneven pressure on gaskets or manifolds, eventually causing leaks or structural failure. Our genuine Sinotruk nuts are forged from high-tensile steel and treated to withstand extreme heat cycles, ensuring that once you torque them down, they stay put.
