Line Hardware U Bolts are hot-dip galvanized carbon steel clamps designed to secure cross arms, conductors, and brackets to cylindrical poles, available in various sizes and compliant with international standards.
WANGYUAN Line Hardware U Bolts Series are designed for clamping and securing cross arms, conductors and equipment brackets to cylindrical poles in distribution lines and substations. Made of hot-dip galvanized carbon steel, the U-shaped bend wraps around the pole profile with parallel threaded legs providing balanced clamping force. Available in a range of diameters, span widths and leg lengths. All products comply with relevant international standards.

The symmetric U-shaped geometry provides balanced clamping force on both legs, ensuring uniform pressure distribution around cylindrical poles without localized stress concentrations. This prevents bracket slippage under wind sway and conductor tension.
Manufactured from high-tensile carbon and alloy steels, the U-bolts withstand significant clamping and shear loads. Safety wire holes at threaded ends allow installation of locking wires to prevent nut loosening under vibration.
Complete hot-dip galvanizing coats both external surfaces and thread interiors with a uniform zinc layer, providing comprehensive long-term protection against rust in coastal, industrial and high-humidity environments.
Pre-assembled with matching nuts and flat washers, the U-bolts are ready for immediate on-site installation using standard wrenches. The comprehensive size range accommodates various pole diameters and bracket thicknesses.
