Electrical Utility Hardware

Electrical utility worker installing components on power pole with insulators and fasteners for transmission lines

TUHU Fasteners supplies electrical utility hardware tailored for pole lines, substations, grounding systems, and equipment mounting.

We offer structural bolts, anchor rods, bent anchor bolts, turnbuckles, eye bolts, and fully threaded rods—designed for high-conductivity environments, outdoor exposure, and high-load stability.

Fasteners are available in carbon steel or stainless steel, with HDG, black oxide, or zinc plating to match site-specific corrosion and conductivity requirements.

Supported Standards:

✔ ASTM A325 / A490, A307, A449, F1554
✔ ASTM A153, A123 (for galvanizing)
✔ ISO 898-1, ISO 3506 (for stainless)
✔ EN 15048, EN 1090
✔ BS 7419
✔ DIN 580 / DIN 529 (eye bolts & anchor bolts)
✔ AASHTO M314 / M164

Material & Finish Options for Electrical Utility Hardware

Fasteners used in electrical utility systems are commonly made from carbon steel for strength or stainless steel where superior corrosion resistance is needed—such as coastal substations or high-humidity areas.

To withstand outdoor exposure and electrical field environments, common coatings include:

Hot-Dip Galvanizing (HDG) – Offers excellent rust resistance for poles, grounding rods, and transformer pads.
Zinc Plating – Used for interior or secondary applications.
Black Oxide – Ideal for enclosed non-exposed connections.

At TUHU Fasteners, we supply finish combinations tailored for electrical poles, substation structures, wire bracing, and equipment mounting in compliance with utility-grade performance standards.
