OEM 800144043 The XCMG Hex-Head Flange Screws 800144043 are genuine OEM fasteners engineered to secure critical joints on XCMG hydraulic excavators.
Identified by part number 800144043, these hex-head flange screws clamp engine, hydraulic and structural components with high, even preload.
They are manufactured from high-strength alloy steel, heat treated for tensile strength, and thread-rolled for fatigue resistance.
The integrated flange spreads clamping load and removes the need for a separate washer, simplifying installation and improving reliability.
Exact OEM thread size, length and grade guarantee a direct replacement that meets the original torque specification without modification.
The 800144043 Hex-Head Flange Screws are made from high-strength alloy steel, heat treated to Class 10.9 for dependable clamping force.
Their thread-rolled profile increases fatigue resistance, helping the screws survive continuous vibration on working excavators.
The integrated serrated flange spreads load and bites into the mating surface, resisting loosening without a separate washer.
Exact OEM thread size, length and grade allow a direct replacement that meets the original torque specification.
A zinc-plated finish resists rust and chemical attack, extending service life in humid, dusty or coastal environments.
Because the screws are genuine XCMG components, they preserve warranty coverage and maintain compatibility with other OEM parts.
Production starts with certified alloy steel wire that is checked for chemical composition and hardenability before release.
Screws are cold forged, thread rolled and heat treated on computer-controlled lines that hold dimensions and grade to exact tolerances.
After heat treatment, each screw is plated and inspected for thread quality, head dimensions and coating thickness.
Batch records let XCMG trace each 800144043 screw back to its raw material lots, so any quality issue can be identified quickly.
Sample screws from each batch undergo tensile testing and hardness testing to prove long-term durability and stable performance.
Hex-head flange screws clamp critical joints so components stay firmly in position under load and vibration.
The 800144043 screws maintain high preload at both low and high engine speeds, keeping bolted joints tight.
Stable clamping protects the flywheel, coupling and transmission from shock loads, reducing the chance of premature failure.
By preventing joint movement, the screws also reduce noise and vibration, improving comfort for the operator.
When the screws work correctly, connected parts stay aligned and the machine frame experiences less stress and cracking.
Inspect the screws during routine service for corrosion, thread damage or loss of torque, and replace any worn unit with genuine 800144043 screws.
The 800144043 Hex-Head Flange Screws install with standard hand tools, keeping downtime and labour costs low during repair.
Park the excavator on firm level ground, shut down the engine, and allow the affected assembly to cool.
Remove the old screws, inspect the threaded holes for damage, and clean all mating surfaces free of oil and debris.
Insert the new screws by hand, making sure the flange seats flat against the component surface without cross-threading.
Tighten the screws evenly in a cross pattern to the specified torque value using a calibrated torque wrench.
Start the engine at low idle, check for unusual noise or vibration, and run through full function cycles before returning to work.
Choosing the genuine 800144043 Hex-Head Flange Screws pays back over time by preventing joint loosening and component damage.
A failed screw can allow components to shift, causing misalignment, vibration and costly repairs to the engine or drivetrain.
The durable construction of these screws keeps clamping performance consistent across a long service life, reducing replacement frequency.
Reliable clamping also extends the life of connected components such as the flywheel, coupling, transmission and frame.
Field data from large construction and mining fleets shows genuine XCMG fasteners reduce vibration-related downtime significantly.
The screws remain serviceable for years under normal operating conditions, removing the need for premature replacement and lowering inventory costs.
XCMG applies sustainable manufacturing principles to the 800144043 screws through recyclable steel content and energy-efficient processes.
The extended service life, often exceeding 10,000 hours in normal conditions, cuts material waste and lowers the environmental footprint.
Preventing joint loosening also avoids secondary damage and fluid leaks, which supports regulatory compliance and responsible site management.
Steel materials are free from restricted substances and comply with RoHS and REACH rules for safe handling and disposal.
Selecting genuine XCMG fasteners supports responsible equipment management while delivering superior operational reliability.
The precision-engineered design allows long, dependable service, which minimises resource consumption across the working life of the machine.
The 800144043 Hex-Head Flange Screws are stocked in XCMG regional distribution centres across North America, Europe, Asia and Australia.
Every unit is wrapped with anti-rust protection inside a fitted carton, shielding it from impact and moisture during transit.
For fleet-wide orders, XCMG offers volume pricing and consolidated freight options that reduce procurement costs and simplify inventory planning.
Real-time stock visibility and dedicated supply chain support help fulfil urgent requests quickly, shortening downtime and keeping excavators productive.
Sturdy packaging preserves the factory condition of the screws until installation, preventing damage that can occur with poorly stored spare parts.
With the XCMG global aftermarket network behind it, you can depend on consistent quality and availability to keep your fleet at full capacity.
Every 800144043 Hex-Head Flange Screw comes from an ISO 9001 and ISO 14001 certified plant with full material traceability.
Incoming alloy steel wire is tested for chemical composition, hardenability and surface quality before release to production lines.
During manufacturing, thread dimensions, head geometry, flange diameter and coating thickness are monitored continuously by trained operators.
Post-production checks include dimensional verification, hardness testing and torque testing to confirm each screw meets specification.
Sample screws from each batch undergo tensile testing and salt spray testing to prove long-term durability and stable clamping performance.
Only screws that pass every quality gate are released, so you receive a dependable, high-performance fastener every time.
Cheap aftermarket screws often use lower-grade steel, incorrect heat treatment or poor thread quality that leads to rapid failure.
Those shortcuts lead to joint loosening, component misalignment and poor reliability in demanding construction and mining conditions.
The genuine 800144043 is built to exacting XCMG standards, delivering correct fit, reliable clamping and durable performance in the field.
Its high-strength alloy steel and precise thread rolling provide consistent results, lowering the chance of expensive joint failures and machine downtime.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and maintains compatibility with other OEM systems on the machine.
