– Model: A210204000232 (Standardized model, can directly replace screws of the same specification, eliminating the risk of model mismatch)
– Material: High-strength 1045 carbon steel (heat treated with quenching and tempering, hardness reaches HRC 28-32, tensile strength ≥600MPa, strong shear resistance)
– Surface treatment: blackening/galvanizing (optional), improves rust and wear resistance, suitable for humid and outdoor working environments, and meets salt spray test standards.
– Specifications and dimensions: M6×20mm (nominal diameter 6mm, effective length 20mm, cross-groove pan head design, countersunk hole installation is more aesthetically pleasing)
This screw boasts high adaptability and is primarily used for fixing cab and interior panels in engineering machinery, securing wiring, and connecting small steel structure nodes. It is widely used in Sany equipment and various general-purpose heavy machinery. Its precise thread profile design perfectly matches the original factory mounting positions, allowing for quick assembly without adjustment. It effectively solves the risk of loosening in vibration environments and supports bulk purchasing and engineering repair replacement. The screw strictly adheres to industrial manufacturing standards, undergoing quenching and surface anti-corrosion treatment. Full-process testing ensures dimensional accuracy and thread integrity, eliminating the risk of breakage and stripping. It is suitable for harsh outdoor, high-temperature, and dusty construction environments, balancing quality and cost-effectiveness.
