XCMG XE2000 Excavator Special Screws (M12×40): Part No. 805139877

In the structural connections and component fixing of the XCMG XE2000 excavator, screws are the “basic fastening units” that maintain the overall stability of the equipment. Especially in key parts such as the cab frame, hydraulic pipeline supports, and engine accessories, the dimensional accuracy, tensile strength, and anti-loosening performance of screws directly determine the safety of component connections. If the screw specifications are off or the strength is insufficient, it is easy to loosen or strip under high-frequency vibration conditions, and even cause components to fall off or the structure to deform, seriously affecting the safety of equipment operation. Our 805139877 screw is specially customized for the XE2000 model, precisely matching the M12×40 (thread diameter × length) specification requirements. Manufactured in strict accordance with XCMG’s original fastener technical standards and drawing parameters, it undergoes four precision tests from thread accuracy, shank diameter to head thickness: thread accuracy reaches 6g level, with complete and flawless tooth profiles, ensuring perfect meshing with nuts or threaded holes; shank diameter error ≤ ±0.04mm, length deviation controlled within ±0.3mm, and head thickness tolerance ≤ ±0.1mm. It can accurately fit the XE2000’s preset mounting holes, allowing for direct tightening without additional tapping or grinding, completely eliminating potential problems such as installation jamming and insufficient tightening force caused by size mismatch, thus providing a solid foundation for equipment structural connections.

The dual enhancement of materials and manufacturing processes gives this screw exceptional tensile strength and rust resistance. The screw body is made of high-quality 4.8 grade carbon steel, cold-forged. Compared to ordinary casting, its internal grains are finer, resulting in a tensile strength exceeding 400MPa and a yield strength exceeding 320MPa. It can easily withstand the vibration loads and structural stresses during XE2000 operations, and is less prone to shank breakage or head deformation with long-term use. The surface is hot-dip galvanized, with a zinc layer thickness exceeding 85μm, forming a dense rust-proof protective layer. This effectively resists rust from mud and water immersion, dust corrosion, and humid environments during mining and construction. A 48-hour salt spray test showed no obvious rust marks, preventing the screw from becoming difficult to disassemble or losing strength due to corrosion. Meanwhile, the screw head features an internal hexagonal recess design, allowing for precise force application when used with a dedicated wrench. This design prevents slippage and damage during tightening, and the internal hexagonal structure reduces the space occupied by the head, making it suitable for the compact component installation environment of the XE2000. The thread surface is phosphated, resulting in a stable coefficient of friction between 0.12 and 0.15, enhancing the self-locking performance between threads and reducing the risk of loosening under high-frequency vibration. Compared to ordinary smooth thread screws, the anti-loosening effect is more than 3 times better.

Whether you’re a maintenance technician on an engineering team needing to replace worn, rusted, or damaged screws during equipment maintenance, or a parts distributor looking to stock highly compatible and reliable fasteners, the 805139877 screw (M12×40) is a cost-effective choice.
