The Hot Dip Galvanized ASTM A153 Double Arming Bolt is designed for robust and secure connections on utility poles and crossarms. Manufactured from high-quality carbon steel, each bolt is hot-dip galvanized to meet ASTM A153 standards, ensuring excellent resistance to corrosion in outdoor and high-voltage environments.
Precision-machined threads ensure firm installation
Galvanized finish prevents rust and prolongs service life
Ideal for harsh weather and high-humidity environments
Compatible with most pole line hardware systems
Maintains strength under load and long-term exposure
The Double Arming Bolt is widely applied in power transmission and distribution projects. It is ideal for connecting crossarms to utility poles, especially in overhead line systems. Thanks to its corrosion-resistant coating and strong mechanical properties, it performs reliably in environments such as:
Coastal and humid regions
Rural and mountainous electrical grids
Suburban utility pole installations
Heavy-duty infrastructure and outdoor electrical setups
Renewable energy systems like wind or solar farms
