Cold Drawn Hexagonal Steel Bar | High-Strength, Ready-to-Use Fastener Base Material
Product Overview
Our Cold Drawn Hexagonal Steel Bar is precision-engineered to provide superior dimensional accuracy across flats (A/F), excellent surface quality, and enhanced mechanical strength. The cold drawing process ensures sharp, well-defined corners, a smooth, bright surface, and consistent quality, making it the ideal raw material for the cost-effective mass production of high-performance fasteners and structural components.
Key Advantages
-
Precise Across-Flats (A/F) Dimensions: Tight tolerances on the hexagonal dimensions ensure perfect wrench grip and easy assembly, minimizing slippage.
-
Sharp, Consistent Corners: Clean 120-degree angles provide optimal contact for machining and tool engagement.
-
Superior Surface Finish: The bright, smooth surface reduces friction and tool wear during machining, and is often ready for use without further processing.
-
Enhanced Strength & Hardness: The cold working process increases tensile and yield strength, resulting in more durable end products.
-
Material & Processing Savings: As a near-net-shape product, it significantly reduces machining time and material waste compared to starting with round stock.
