Double Arming Bolt

A Double arming bolt is a high-strength fastening component used in overhead power line construction to secure double crossarms, insulators, brackets, and associated pole-line hardware. Manufactured from durable steel and typically hot-dip galvanized for corrosion resistance, it provides reliable clamping force and structural stability under mechanical loads, vibration, and outdoor exposure. Its dimensions, thread specifications, and mechanical strength must match the requirements of the pole assembly and applicable utility standards.

Key Features:

• High mechanical strength: Withstands specified tensile and shear loads in overhead line assemblies.
• Corrosion protection: Hot-dip galvanized coating helps resist rust and environmental degradation.
• Secure fastening: Threaded ends accommodate compatible nuts and washers for firm connections.
• Durable construction: Designed for long-term service in outdoor electrical infrastructure.
• Dimensional accuracy: Consistent bolt length, diameter, and thread geometry support proper installation.
• Wide compatibility: Suitable for double crossarms and compatible pole-line fittings.
• Quality assurance: Can be inspected for dimensional tolerances, coating thickness, thread integrity, and mechanical properties.
