| Parameter | Details |
|---|---|
| Diameter | 1mm, with strict dimensional tolerance control within ±0.005mm to ensure consistency and interchangeability |
| Material Hardness | Carbon steel material with a hardness range of HB 180 - 220, providing a good balance of hardness and toughness for small-scale load-bearing and operational needs |
| Surface Roughness | Ra≤0.8μm, achieved through fine polishing, ensuring a smooth surface that reduces friction and wear during use |
