803591223 Cross Recessed Countersunk Head Screw XCMG XDE130 Electric driving dump truck spare parts

The 803591223 cross recessed countersunk head screw can solve problems such as protruding parts, poor fit on panels, loose or slipping screws, uneven tightening force, and component vibration and abnormal noise. It is suitable for replacing old screws, overhauling and tightening equipment panels, assembling new machines from the original factory, and maintaining and upgrading precision fastening systems for complete machines. The product is made of original high-strength fastening steel, manufactured through precision thread rolling, hardening and tempering, and rust and corrosion prevention processes. The threads have precise engagement and high degree of engagement, and are characterized by pressure resistance, wear resistance, shock resistance, loosening prevention, and resistance to stripping and corrosion. It is suitable for harsh working conditions such as high-frequency vibration and dust and oil contamination in engineering machinery, achieving a flat and reliable embedded fastening effect.

Core technical parameters:

– Product Model: 803591223
-Product Name: Cross Recessed Countersunk Head Screw
– Material specifications: Original high-strength high-quality steel, with sufficient hardness and good toughness, precise and wear-resistant threads, not easy to strip, rust, break or fail.
– Manufacturing process: Precision one-piece molding, cross groove and countersunk head are precisely machined, surface anti-rust treatment, and passed the original factory torque tightening quality inspection.
– Performance and working condition adaptability: tight engagement, stable locking, shock resistance and anti-loosening, suitable for engineering machinery plate flat fastening operation conditions.
– Structural features: Original factory standard countersunk head specifications, flat assembly without protrusion, cross groove for easy alignment, efficient disassembly and assembly, and high fit.

This product undergoes specialized testing at the factory, including torque load capacity, thread engagement, vibration resistance, anti-loosening, and corrosion resistance, meeting the original equipment manufacturer (OEM) assembly standards for construction machinery. When installed, it ensures a flat, embedded fastening on equipment panels, preventing loose screws, misaligned components, and abnormal operating noises. It improves the overall assembly flatness and structural stability, reduces losses from fastening point failures, minimizes maintenance costs, and provides long-term, stable operation of the equipment’s precision fastening system.
