803591187 Hexagon Head Indented Assembly Bolt XCMG XDE130 Electric driving dump truck spare parts

The 803591187 hexagon head indented assembly bolt effectively solves problems such as protrusions, large gaps in fit, misalignment during fastening, vibration loosening and slippage, and uneven stress during assembly in precision component assembly. The product is compatible with XCMG excavators, cranes, aerial work platforms, loaders, and other engineering machinery. It is widely used for assembling and locking electrical precision components, embedded mounting points, plate-type fitting components, and precision equipment housings. Utilizing the standard hexagonal head disassembly and assembly structure and recessed recessed design, it achieves a flat and snug fit, avoiding interference from the equipment structure caused by protruding bolt ends. It evenly distributes assembly pressure, improving the flatness and overall stability of precision component assembly, and is suitable for high-frequency vibration and precision assembly operations. This product is precision-forged from high-strength alloy steel, undergoing precision thread rolling, refined recessed structure, overall heat hardening, and rust and corrosion protection passivation treatment. It has passed comprehensive performance tests for tensile and compressive strength, vibration resistance, precision locking, and fatigue resistance, possessing core advantages such as precise structure, secure locking, stable strength, and high fit.
