800169085 hexagonal head screw XCMG XE2000 excavator spare parts

XCMG Original Excavator Hex Head Screw 800169085 – Core Fastening Component for XE2000 Model

If you need to replace the hex head screws on your XCMG XE2000 excavator, the XCMG genuine hex head screws (part number 800169085) are a reliable choice. As the “foundation” for the XE2000’s structural components, hydraulic parts, electrical supports, and other critical parts, they are responsible for connecting and securing components, preventing loosening and detachment caused by operational vibrations. They are a core component for construction companies and excavator maintenance teams worldwide to ensure equipment structural stability.

Why choose XCMG XE2000 genuine hex head screws 800169085?

1. Original factory precise fit, installation without deviation.

Manufactured strictly according to XCMG XE2000 component installation dimension standards, the thread specifications (pitch, diameter), screw length, and hexagonal head size are perfectly matched with the original mounting holes, allowing direct replacement of old screws without the need for tapping or adjusting the hole diameter. This avoids thread stripping and head jamming issues caused by incompatible dimensions in universal screws, ensuring a perfect fit with nuts and washers for precise tightening.

2. High-strength material, pull-out and twist-resistant.

Made of high-quality 40Cr alloy structural steel, and treated with quenching and tempering heat and surface galvanizing, it has a tensile strength of over 800MPa and a yield strength exceeding 640MPa, meeting the ISO 898-1 high-strength screw standard. It can withstand the vibration, impact, and tensile forces of components during XE2000 operation, and is less prone to screw breakage and thread deformation over long-term use. The head is less likely to slip or crack during tightening, extending its service life by 50% compared to ordinary carbon steel screws.

3. Precision thread machining ensures reliable fastening.

The threads are machined using a rolling process, resulting in a full tooth profile and a precision of 6g, ensuring a tight, gapless meshing with the nut. The screw surface is smooth and burr-free, allowing for easy screwing into the mounting hole during assembly and reducing thread wear. Once tightened, a stable preload is generated, effectively preventing thread loosening even under high-frequency vibration conditions. This ensures the secure connection of critical components such as the machine body and hydraulic parts, avoiding component displacement failures caused by loose screws.

4. Rust and corrosion resistant, adaptable to complex environments.

The surface is hot-dip galvanized and passivated, with a coating thickness of 8-12μm. It has undergone salt spray testing for over 48 hours, resisting corrosion from rain, dust, and oil commonly encountered in XE2000 operations. In humid mining environments and muddy agricultural and forestry settings, it is less prone to rust and jamming, ensuring smooth screw removal during later maintenance and reducing maintenance difficulty.

Fully adaptable to various scenarios

The 800169085 hex head screw maintains stable fastening performance in various operating scenarios of the XE2000:
Heavy-duty mining operations: withstand strong vibrations and heavy tensile forces, tighten hydraulic pump supports and boom connections to prevent components from loosening or shifting;
Infrastructure earthwork construction: Suitable for long-term continuous operation, fixing the machine body cover and electrical box shell to prevent parts from falling off due to vibration;
Building foundation engineering: resisting the impact of frequent start-stop cycles, tightening the components of the slewing mechanism, and ensuring stable equipment steering.
Agricultural and forestry operation scenarios: resist moisture and pesticide residue corrosion, fix cab accessories and pipeline clips to ensure long-term stability of parts.

Flexible procurement options: Supports single-box retail (50/100 pieces per box) and bulk wholesale, offering tiered pricing for repair shops and distributors to meet daily repair parts and bulk inventory needs.
Select genuine screws to secure the structural foundation of the XE2000.

The fastening of components in the XCMG XE2000 is the “basic line of defense” for safe operation of the equipment. The original hex head screws 800169085, with their precise fit, high-strength materials and reliable fastening, build a solid structural stability barrier for the equipment: reducing loosening failures, lowering maintenance costs, extending the service life of components, and helping the equipment to operate efficiently and safely.
