800144043 hexagon head flange screw XCMG XE2000 excavator spare parts

XCMG XE2000 excavator hex head flange bolts (part number 800144043): Strengthening the core, reinforcing the connection between components.

In the component assembly system of the XCMG XE2000 excavator, the hexagonal head flange bolt is the “core fastener” that enables rigid connections of key components. This bolt, part number 800144043, with its high-strength fastening performance and precise dimensional design, provides reliable assurance for the stable connection of various equipment components and is an important basic spare part for maintaining the structural integrity of the excavator.

1. Precisely adapts to the connection of core components.

Specifically designed for specific assembly parts of the XCMG XE2000 excavator, this design perfectly matches the bolt hole specifications and connection requirements of the corresponding components through precise thread dimensions and flange face design. The thread precision reaches 6g level, and the flange face flatness is precision-machined to ensure a tight fit with the surface of the connected parts, guaranteeing uniform force distribution during equipment vibration operation and preventing loosening caused by localized stress concentration.

2. High-strength materials withstand heavy impacts.

Made of high-strength alloy structural steel through quenching and tempering, the screws have a tensile strength of 8.8 or higher, exhibiting excellent shear and fatigue resistance. Designed to withstand the continuous vibration and impact loads encountered by the XE2000 during heavy-duty operations, the screws maintain a stable preload over long periods, minimizing the risk of breakage or stripping. The surface undergoes galvanizing and passivation treatment, forming a uniform protective film that effectively resists moisture and dust corrosion in the working environment, preventing rust from affecting fastening performance.

3. Original manufacturer quality control ensures reliable connection.

As an original XCMG spare part, this hexagonal head flange bolt strictly adheres to the original manufacturer’s quality control standards. From raw material smelting to finished product processing, every step undergoes rigorous testing to ensure that key indicators such as thread accuracy, hardness, and torque meet the standards. The anti-slip tooth design on the flange face has been optimized and tested to enhance friction with the connected parts, further improving the anti-loosening effect. The quality fully meets the connection requirements of equipment under heavy-duty conditions.

4. Standard installation improves maintenance efficiency.

Featuring a standardized hexagonal head design, compatible with universal wrenches, operators can quickly complete installation and tightening without special tooling. The screw length and diameter parameters have been optimized by the manufacturer to precisely meet connection depth requirements, preventing loose connections due to excessively short screws or interference due to excessively long screws. In routine maintenance, stable tightening performance reduces component displacement failures caused by loose screws, lowering equipment downtime for repairs and saving on operating costs.

To ensure the stability and safety of component connections on the XCMG XE2000 excavator, hexagonal head flange bolts (part number 800144043) are a reliable choice. Precise fit design, high-strength material properties, stringent original factory quality control, and convenient installation and maintenance work together to build a solid connection defense for the equipment, helping the excavator maintain structural stability during heavy-duty operations.
