| Additional notes on strength rating: The higher the strength rating of the screw (e.g., 12.9), the greater the tightening torque it can withstand, and the higher the corresponding recommended torque; Specification differences: Even if the nominal diameter of the screw is the same (e.g., M6), the recommended torque will differ depending on the application scenario (general/base). The corresponding parameter needs to be selected according to the actual assembly requirements. | ||
