Description
This valve cover bolt is a high-strength fastener for fixing the valve cover (cylinder head cover) of FAW heavy truck engines. It evenly compresses the valve cover gasket between valve cover and cylinder head to prevent oil leakage and oil mist escape from the joint surface. Made of premium alloy steel with quenching and tempering heat treatment, it maintains stable tensile strength and excellent fatigue resistance under continuous engine vibration and high-temperature working conditions. Precision rolled threads ensure consistent torque bearing capacity and reliable assembly, resisting loosening. Each bolt passes hardness inspection and thread inspection before shipment. It solves oil seepage caused by bolt elongation, thread slipping and loosening, and serves as an essential replacement fastener for engine top overhaul.
