330400329 U-bolt XCMG XDE130 Electric driving dump truck spare parts

The 330400329 U-bolt is an original equipment manufacturer (OEM) fastener from XCMG, specifically designed for XCMG excavators, cranes, and other construction machinery. It addresses common issues such as stripped threads, loosening, poor corrosion resistance, and easy breakage. Widely used in pipe fixing, chassis supports, and base connections, it is a key component for equipment maintenance and installation. This product conforms to XCMG’s OEM standards and the JB/ZQ4321-2006 industry specification, using Q345B high-strength carbon steel or 304 stainless steel. It is cold-bent, thread-rolled, and surface-treated for corrosion protection, making it suitable for the complex operating conditions of construction machinery, including high temperatures, high dust levels, and high-frequency vibrations. It firmly secures various components, preventing loosening and displacement, and extending equipment lifespan.
