Six Flat Sides for Positive Wrenching
Our copper hex bar has a six-sided cross-section. This shape serves a clear purpose. The flat sides give you a secure gripping surface. Operators can hold it easily with a wrench. Round bars slip when you try to tighten them. Hex bars do not. This makes assembly and disassembly faster and safer. Our team controls the across-flats dimension carefully. The angle between sides must stay consistent. Our equipment holds these tolerances well. We also check for straightness. Even slight bends can cause problems during CNC machining. Our workers have developed efficient inspection routines for hex geometry.
Stock Sizes and Material Data
We stock copper hex bar in Φ6, Φ8, Φ10, Φ18, Φ20, and Φ22. These numbers refer to the circumscribed circle diameter. The material is T2 copper. Production follows GB/T5585.1-2026. Copper purity reaches Cu≥99.90%. Impurities stay below 0.10%. Conductivity measures ≥97.3% IACS. Resistivity at 20°C does not exceed 0.0177 Ω·mm²/m. Density is 8.9 g/cm³. Tensile strength ranges from 220 to 260 MPa. Yield strength stays above 170 MPa. Hardness falls between 65 and 90 HV. Elongation is 17% or higher.
Where Hex Bars Perform Best
Mechanics and assembly workers prefer hex bars for connections that need regular maintenance. Electrical equipment uses them for terminal posts and connection bolts. Copper fasteners of various types rely on this shape. The hex profile also makes torque application more consistent. You get better control over tightening force. This reduces the risk of overtightening. It also makes removal easier. Our customers in the electrical fitting industry order this product regularly. We also supply manufacturers who produce custom fasteners. The demand for hex bars remains steady because of their practical advantages.
Production and Order Information
We run our CNC programs to control the six-sided dimensions accurately. Every batch has flat and even surfaces. Before packaging, we inspect the surface condition. Third-party inspection is welcome at our factory. Our raw material inventory stays well-stocked. We start production immediately after order confirmation. Standard sizes ship within one week. Custom sizes take one to two weeks. The minimum order is 1000 kilograms. Mixed specifications are allowed in one order. We accept USD, EUR, and CNY for settlement.
