Product Overview
Cold Drawn Hexagon Steel Bar (Cold Drawn Hex Bar) is a high-precision cold-finished steel profile processed by professional cold drawing technology from hot rolled steel raw materials. After cold drawing treatment, the product obtains ultra-smooth bright surface, accurate hexagonal dimension, strict tolerance and excellent straightness. It effectively reduces machining allowance, eliminates secondary polishing procedures, and is a core raw material for high-efficiency CNC turning and precision fastener manufacturing.
