803591075 Inner Hexagon Screw XCMG XDE130 Electric driving dump truck spare parts

The 803591075 inner hexagon screw effectively solves common problems such as loose equipment fasteners, component misalignment, excessive assembly clearance, operational vibration and abnormal noise, stripped or broken screws, and leakage due to locking failure. It is suitable for scenarios including old part replacement, equipment maintenance, original factory assembly of new machines, component reinforcement, and fastener repair. The product uses original high-strength alloy steel, processed through precision forging, precision milling, tempering and hardening, and rust and corrosion prevention. The threads are precise, the engagement is tight, and the locking capacity is strong. It possesses high hardness, high strength, tensile strength, wear resistance, fatigue resistance, and corrosion resistance, making it suitable for harsh working conditions such as high-frequency vibration, continuous load, dust and oil contamination, and large outdoor temperature differences in engineering machinery, ensuring stable equipment structural fastening.

Core technical parameters:

– Product Model: 803591075
-Product Name: Inner Hexagon Screw
– Material specifications: High-strength alloy steel with excellent hardness and tensile strength, wear-resistant and corrosion-resistant, and not easily deformed or broken under stress.
– Processing technology: One-piece precision forging, precision milling of threads, tempering and hardening, rust prevention and passivation, all following the original factory’s precision quality inspection process.
– Performance and working condition adaptation: precise thread engagement, stable locking, vibration and tensile resistance, corrosion resistance, and adaptability to high-frequency operating conditions of equipment.
– Structural features: Original factory standard specifications, easy to disassemble and assemble, uniform force distribution, high hole position adaptability, effectively reducing operation and maintenance costs.

This product undergoes multiple specialized tests at the factory, including hardness, thread precision, locking load-bearing capacity, vibration fatigue resistance, and rust and weather resistance, meeting the original equipment manufacturer (OEM) assembly standards for construction machinery. After installation, it precisely matches the locking requirements of the equipment, ensuring a tight, secure, and anti-loosening grip. It completely resolves issues such as loose screws, stripped threads, breakage, and corrosion, improving the overall assembly stability and structural integrity of the machine. This reduces abnormal noises, component wear, and downtime, lowering maintenance frequency and parts consumption, and providing long-term protection for the safe, stable, and efficient operation of construction machinery.
