803591190 Cross-Plate Head Screw XCMG XDE130 Electric driving dump truck spare parts

The 803591190 cross-plate head screw effectively solves common problems such as loosening of small parts, slippage and disengagement of the Phillips head, poor thread engagement, screw corrosion and jamming, insufficient tightening torque, loosening due to equipment vibration, breakage due to twisting under stress, and abnormal noise due to assembly gaps. It is suitable for replacing old Phillips head screws in construction machinery, inspecting precision assembly points, tightening and rectifying small parts, original equipment assembly for new machines, and maintenance and reinforcement of the fine structure of the whole machine. The product uses original high-strength high-quality steel, and undergoes precision thread rolling, precise stamping of the Phillips head, and surface anti-rust passivation hardening process. The threads are fine and regular, with high engagement accuracy. The Phillips head is evenly stressed and does not slip. The overall hardness is sufficient, with torsional and tensile strength, and it is not easy to deform and break. It has good rust prevention, oil resistance, and corrosion resistance. It can adapt to the harsh working conditions of construction machinery with high-frequency vibration, dust and oil adhesion, and humid and temperature fluctuations, and ensures long-term tight and stable assembly of various small precision parts.

Core technical parameters:
