ActiveDimension，shape，weight and tolerance for cold-drawn round，square and hexagonal steels
冷拉圆钢、方钢、六角钢尺寸、外形、重量及允许偏差
Application Summary AI generated
This standard specifies the dimensions, cross-sectional shapes, weight, and permissible deviations for cold-drawn round, square, and hexagonal steel bars. It is applied in the manufacturing and quality inspection of precision steel components, such as machine parts, fasteners, and tool blanks, where tight tolerances and consistent shapes are required for subsequent machining or assembly.
