OEM 804002469 The XCMG Hex Socket Flat-End Set Screw (804002469) is a genuine OEM precision fastening component engineered to provide secure, reliable clamping and positioning for critical assemblies in XCMG hydraulic excavators. This high‑strength set screw, identified by part number 804002469, is designed for applications requiring a flat‑end engagement surface, ensuring even load distribution and damage‑free contact with mating components under the extreme vibration, shock, and torque conditions typical of construction, mining, and demolition operations.
Manufactured from high‑quality alloy steel with precision‑rolled threads and a hardened, heat‑treated core, the 804002469 hex socket flat‑end set screw delivers exceptional tensile strength, wear resistance, and long‑term durability. Its exact OEM dimensions, thread pitch, and length guarantee a direct replacement without modification, ensuring seamless integration with your XCMG excavator’s existing fastening points and preserving the machine’s original clamping force and safety margins.
The 804002469 screw features a precisely formed hex socket drive that allows for accurate torque application with standard hex keys, a flat‑end tip that provides a stable bearing surface without marring the mating part, and a corrosion‑resistant black oxide or zinc‑plated finish that withstands harsh environmental conditions. By providing a reliable, reusable fastening solution, this set screw plays an essential role in preventing loosening, reducing maintenance frequency, and extending the service life of your excavator’s structural and mechanical assemblies in the toughest working conditions.
The 804002469 hex socket flat‑end set screw is manufactured from high‑strength alloy steel with a precisely controlled heat‑treatment process that ensures optimal hardness and core toughness. The precision‑rolled threads provide consistent engagement and excellent resistance to stripping, while the flat‑end tip distributes clamping force evenly without marring the contact surface, making it ideal for applications where component protection is critical.
The hex socket drive allows for accurate torque application using standard hex keys, reducing the risk of cam‑out and ensuring repeatable, reliable clamping. The corrosion‑resistant black oxide or zinc‑plated finish protects against rust and chemical attack, maintaining the screw’s integrity even in humid or chemically aggressive environments.
By providing a secure, non‑marring fastening solution, the 804002469 set screw plays a vital role in maintaining the alignment and stability of critical assemblies, such as pivot pins, bearing housings, and hydraulic component mounts, where precise positioning and consistent clamping force are essential.
The 804002469 set screw is produced using advanced cold‑heading, thread‑rolling, and heat‑treatment processes that achieve tight tolerances on all critical dimensions, ensuring consistent fit and performance across every unit. The alloy steel is selected for its excellent combination of strength, ductility, and fatigue resistance.
The thread‑rolling process work‑hardens the thread flanks, increasing their resistance to galling and stripping compared to cut threads. The heat‑treatment process is precisely controlled to achieve the specified hardness (39–44 HRC) while maintaining sufficient core toughness to withstand shock loading.
The surface finish is applied using a uniform coating process that ensures consistent coverage and excellent adhesion, providing a durable, corrosion‑resistant layer that maintains its protective properties even after repeated installation and removal.
After production, each screw undergoes dimensional inspection, hardness testing, and thread verification to ensure it meets XCMG’s stringent quality standards. Sample units from each production batch are subjected to torque‑to‑failure testing, salt spray exposure, and vibration loosening tests to validate long‑term performance.
Set screws are fundamental fasteners used throughout the excavator to secure components such as gears, pulleys, collars, and pivot pins to shafts or housings. The flat‑end design is specifically chosen for applications where the screw must bear directly against a flat surface without damaging it, ensuring even load distribution and preventing brinelling or scoring.
The 804002469 set screw ensures that critical assemblies remain securely fastened, preventing loosening due to vibration, thermal cycling, or operational loads. A loose set screw can lead to component misalignment, accelerated wear, and even catastrophic failure, making the reliability of this fastener essential for machine uptime and safety.
Field data from heavy excavation operations shows that machines assembled with genuine XCMG fasteners experience fewer loosening‑related issues and reduced maintenance interventions, improving overall machine availability and reducing repair costs.
The screw’s robust construction and corrosion‑resistant finish protect against environmental factors such as moisture, dust, and chemical exposure, ensuring long‑term reliability of the fastening interface.
Regular inspection of set screws for signs of loosening, wear, or corrosion is recommended; any compromised screws should be replaced promptly with genuine 804002469 components.
The 804002469 hex socket flat‑end set screw is designed for straightforward installation using standard hex keys, minimising downtime and labour costs during routine servicing or component replacement. Before installation, ensure that the threaded hole and mating surface are clean and free from debris or old thread‑locking compound.
Apply a suitable thread‑locking compound (medium strength) if specified by the maintenance manual, then insert the screw and tighten to the recommended torque using a calibrated torque wrench. The hex socket provides a positive drive that reduces the risk of stripping, even under high torque.
After installation, verify that the screw is fully seated and that the component is securely clamped. For critical applications, mark the screw with a torque‑stripe to indicate proper tightening.
During routine maintenance, inspect the set screw for signs of loosening, corrosion, or damage. Retighten as necessary and replace any damaged screws with genuine 804002469 components to maintain optimal clamping force.
Investing in the genuine 804002469 set screw delivers significant long‑term savings by preventing fastening failures, reducing component wear, and avoiding costly downtime that can result from loose or failed fasteners.
A compromised set screw can allow components to shift, leading to misalignment, accelerated wear, and even catastrophic failure. The 804002469’s precise geometry, high strength, and corrosion resistance eliminate these risks, ensuring consistent clamping performance over the life of the machine.
Over a typical 10,000‑hour service life, the screw’s robust construction and corrosion‑resistant finish ensure reliable fastening, reducing the need for frequent retightening or replacement.
By maintaining secure component positioning, the set screw also extends the service life of adjoining parts, further reducing overall maintenance costs.
Field data from large‑scale mining and construction operations shows that using genuine XCMG fasteners reduces fastening‑related downtime by up to 10%.
