803591174 Hexagon Nut XCMG XDE130 Electric driving dump truck spare parts

The 803591174 hexagon nut effectively solves common problems such as loose fasteners, thread slippage, excessive assembly clearance, loosening and misalignment under stress, stripped or chipped threads, surface corrosion and jamming, pressure deformation failure, and equipment structural shaking and abnormal noise. It is suitable for replacing old hexagonal nuts in construction machinery, inspecting equipment fastening points, upgrading structural locking systems, assembling new machines with original equipment, and upgrading and maintaining the overall machine structure. The product is made of original high-strength alloy steel, precision forged, precisely threaded, and surface-hardened for rust prevention. The hexagonal shape is regular and standard, with uniform and symmetrical stress distribution. The threads are highly accurate, tightly engaged, and do not slip. It has strong locking capacity, tensile and compressive strength, and is not prone to chipping, deformation, or fatigue loosening. The surface has excellent rust prevention, corrosion resistance, and anti-aging properties. It is suitable for harsh operating conditions in construction machinery, including high-frequency vibration, heavy loads, outdoor dust and oil contamination, and fluctuating humidity and temperature. It provides long-term locking of various assembly structures, eliminating the risk of structural loosening.

Core technical parameters:

– Product Model: 803591174
-Product Name: Hexagon Nut
– Material specifications: Original high-strength alloy steel, hardened and rust-proofed, with high locking strength, resistance to deformation and impact, and not easy to rust or strip.
– Processing technology: Precision one-piece forging, thread accuracy calibration, surface anti-corrosion reinforcement, and multiple quality inspections for locking pressure, engagement accuracy, and vibration durability.
– Performance and working condition adaptability: It has a stable locking mechanism, strong pressure resistance, and is earthquake resistant and anti-loosening, making it suitable for the fastening conditions of heavy-duty vibration structures in engineering machinery.
– Structural features: Original factory standard hexagonal specification, precise thread engagement, convenient disassembly and assembly, uniform force distribution, eliminating the risk of stripping, loosening, and chipping of threads.

This product undergoes specialized testing at the factory, including locking load-bearing capacity, thread engagement accuracy, vibration resistance, anti-loosening, rust prevention, and weather resistance. It meets the original equipment manufacturer (OEM) and standard fastener assembly standards for construction machinery. Replacing the fastener with a standard fastener strengthens the locking force of the equipment structure, eliminating problems such as loose assembly, structural wobbling, and abnormal operating noise. It improves the overall assembly accuracy and structural stability, effectively extends the service life of fastening points, reduces equipment failures and maintenance costs caused by structural loosening, and continuously ensures that all connection structures of construction machinery are tight, secure, and operate stably for a long time.
