803591211 Hexagonal Head Bolt XCMG XDE130 Electric driving dump truck spare parts

The 803591211 hexagonal head bolt can solve problems such as loose fasteners, poor fit of components, vibration and abnormal noise during operation, stripped or broken bolts, and loose bolts. It is suitable for replacing old bolts, tightening during equipment structural maintenance, original factory assembly of new machines, and maintenance and upgrade of the entire machine’s fastening system. The product is made of original high-strength alloy steel, through precision cutting, hardening and tempering, and rust-proof galvanizing processes. It has high hardness, strong torsional load-bearing capacity, and features compression and shear resistance, wear resistance, corrosion resistance, shock resistance, and anti-loosening properties. It is suitable for harsh working conditions such as high-frequency vibration, heavy-duty operation, and dust and oil pollution in engineering machinery, and firmly locks various mechanical components.

Core technical parameters:

– Product Model: 803591211
-Product Name: Hexagonal Head Bolt
– Material specifications: Original high-strength alloy steel, with sufficient hardness, strong load-bearing capacity, wear-resistant and pressure-resistant, not easy to strip, rust, or break.
– Processing technology: precision one-piece cutting and forming, temper hardening treatment, surface rust prevention zinc plating, and passed the original factory torque and pressure resistance quality inspection.
– Performance and working condition adaptability: sufficient fastening force, shear and compression resistance, shock resistance and loosening prevention, suitable for heavy-duty vibration fastening conditions of engineering machinery.
– Structural features: Original factory standard compatible specifications, precise hexagonal alignment, convenient disassembly and assembly, and secure locking that is not easy to loosen.

This product undergoes specialized testing at the factory, including torsional load capacity, compressive and shear strength, seismic resistance, anti-loosening, and corrosion resistance, meeting the original equipment manufacturer (OEM) assembly standards for construction machinery. After installation, it precisely locks various components of the equipment, preventing loose parts, vibrations, abnormal noises, and misalignment. This improves the overall assembly accuracy and structural stability, reduces equipment failures caused by fastener failure, minimizes maintenance costs, and ensures long-term stable operation of construction machinery.
