Double end bolts are precision-engineered fasteners designed for structural connections in overhead power line and transmission infrastructure. Threaded at both ends with an unthreaded shank in the center, they provide secure clamping of fittings, crossarms, insulators, and steel structures where high tensile strength and long-term reliability are required. These bolts are widely used in utility-scale distribution and transmission projects exposed to mechanical load, vibration, and harsh outdoor conditions.
Key Features:
- High tensile strength: Manufactured from carbon steel or alloy steel to withstand axial loads and dynamic stresses
- Dual-threaded design: Enables firm anchoring between two components using nuts on both ends
- Corrosion resistance: Available with hot-dip galvanized or zinc-plated finishes for outdoor durability
- Dimensional accuracy: Consistent threading and shank tolerances ensure easy installation and alignment
- Standards compliance: Produced in accordance with IEC, ASTM, or ISO specifications
- Versatile application: Suitable for crossarms, pole line hardware, insulator assemblies, and steel structures
