GB/T 342-1997
AbolishedDimension，shape，mass and tolerance for cold-drawn round，square and hexagonal steel wires
冷拉圆钢丝、方钢丝、六角钢丝尺寸、外形、重量及允许偏差
Application Summary AI generated
This standard specifies the dimensions, cross-sectional shapes, mass per unit length, and permissible deviations for cold-drawn steel wires with round, square, and hexagonal profiles. It is applied in the manufacturing and quality inspection of precision steel wires used in mechanical components, springs, fasteners, and structural parts where tight tolerances are required. The standard ensures consistency in procurement and production for industries such as automotive, aerospace, and general engineering.
