803591178 Hexagonal Head Bolt XCMG XDE130 Electric driving dump truck spare parts

The 803591178 hexagonal head bolt can effectively solve common problems such as loose structural fasteners, thread slippage, bolt bending under stress, insufficient assembly tightening, equipment shaking and abnormal noise during operation, screw corrosion and aging, thread chipping and wear, and failure due to heavy load. It is suitable for scenarios such as replacing old hex head bolts in construction machinery, inspecting equipment fastening points, modifying structural connection systems, assembling new machines with original equipment, and maintaining and upgrading the fastening structure of the whole machine. The product is made of original high-strength alloy steel, precision forged, threaded with precision rolling calibration, and surface hardening and rust-proofing passivation. The hexagonal head is regular and standard, with uniform force distribution and no slippage. The screw has high strength and excellent toughness, and the thread tooth profile is precise and full, with tight and smooth engagement. It has strong tensile and compressive load-bearing capacity and is not easy to bend, deform, chip, or break under long-term heavy load. The surface has excellent rust prevention, corrosion resistance, and aging resistance. It can be adapted to the harsh working conditions of heavy-duty operation of engineering machinery, high-frequency vibration, outdoor temperature difference, dust, oil, and moisture corrosion. The long-term locking equipment assembly structure stabilizes the mechanical connection strength of the whole machine.

Core technical parameters:

– Product Model: 803591178
-Product Name: Hexagonal Head Bolt
– Material specifications: Original high-strength alloy steel, hardened and rust-proofed, with high tensile strength, bending resistance, impact resistance, and resistance to corrosion and chipping.
– Processing technology: precision forging, thread accuracy calibration, surface anti-corrosion reinforcement, and multiple rigorous quality inspections for tensile durability, locking accuracy, and shock resistance.
– Performance and working condition adaptability: strong locking force, tensile strength and stability, shock resistance and durability, suitable for heavy-duty high-frequency vibration fastening conditions of engineering machinery.
– Structural features: Original factory standard specifications, precise dimensions, easy disassembly and assembly, tight thread engagement, eliminating the risk of loosening, stripping, and structural breakage.

This product undergoes specialized testing at the factory, including tensile and compressive strength, thread engagement accuracy, shock resistance, durability, rust prevention, and weather resistance. It meets the original equipment manufacturer (OEM) and standard fastener assembly standards for construction machinery. Replacing the fastener with a replacement can effectively strengthen the equipment’s structural locking strength, eliminate problems such as loose assembly, structural wobbling, and abnormal operating noises, improve the overall assembly accuracy and structural stability, extend the service life of fastening points and components, reduce maintenance costs caused by structural loosening and component damage, and continuously ensure the secure, safe, and stable operation of all types of connections in construction machinery.
