The 304 Forged Triangle Eye Bolts for Power Lines are specialized fasteners engineered to secure critical infrastructure in power transmission and distribution systems. Forged from 304 stainless steel—a material chosen for its corrosion resistance and tensile strength—and enhanced with a hot-dip galvanized finish, these eye bolts excel in outdoor, high-voltage environments.
Compliant with IEEE 693 (the standard for substation equipment) and ASTM A193 (for high-temperature bolts), they ensure reliable performance in applications where electrical safety and structural integrity are paramount. Their unique triangle eye design sets them apart, offering superior load distribution compared to traditional round-eye bolts.

Corrosion-Resistant Design:
The combination of 304 stainless steel and hot-dip galvanized coating creates a dual defense against corrosion. The stainless steel core resists rust in humid or industrial environments, while the 80–100 μm galvanized layer adds protection against salt spray and chemical exposure—critical for coastal power lines or industrial substations. This design meets ISO 12944 C5-M standards, ensuring 20+ years of service life without significant degradation.
High Strength and Reliability:
Forging—rather than casting—strengthens the steel grain structure, resulting in a tensile strength of 515 MPa that easily handles loads from 10–100 kN. The triangle eye design distributes stress across three contact points, minimizing pressure on any single area and reducing the risk of eye deformation under tension. Compliance with ASTM A193 ensures they maintain strength at high temperatures, a key feature for power lines near transformers or substations.
Wide Temperature Compatibility:
Operating from -50°C to +300°C, these eye bolts perform in extreme climates. In northern regions, they resist brittleness in sub-zero winters, while in desert areas, they withstand intense heat without losing tensile strength. This stability ensures consistent performance in global power grids, from Arctic transmission lines to tropical substations.
Easy Installation:
The fully threaded shank allows for secure attachment to steel towers or utility poles using standard nuts and washers. The triangle eye’s open design simplifies connection to cables, insulators, or rigging hardware, reducing installation time for linemen. Pre-drilled holes in the eye accommodate shackles or hooks, ensuring compatibility with existing power line components.
Safety-Compliant:
IEEE 693 certification guarantees they meet strict safety standards for electrical equipment, including resistance to arc flashes and short circuits. The 2.5:1 safety factor provides a buffer against unexpected loads, such as ice accumulation or wind gusts, preventing catastrophic failures in power transmission systems. Each bolt undergoes magnetic particle inspection to detect hidden flaws, ensuring reliability in critical applications.
Power Transmission: Overhead power lines use these eye bolts to suspend conductors from steel towers, withstanding tension and wind-induced vibration. They secure insulators to prevent electrical arcing, ensuring safe voltage distribution.
Renewable Energy: Solar farms employ them to anchor panel mounting systems to concrete or steel frames, withstanding wind uplift and temperature fluctuations. Wind turbine guy wires use them to stabilize towers, ensuring structural integrity during high winds.
Construction: Infrastructure projects use them to rig heavy electrical equipment, such as transformers, during substation installation. They secure temporary power lines at construction sites, providing reliable electricity for tools and machinery.
Mining: Underground mines use these eye bolts to suspend electrical cables, withstanding damp conditions and dust without corrosion. Surface mines employ them to secure power distribution systems for heavy machinery.
Transportation: Railway overhead lines rely on them to suspend catenary wires, ensuring consistent power supply to trains. Electric vehicle charging stations use them to secure power cables, withstanding outdoor exposure.
In a recent upgrade to a coastal power grid, these eye bolts replaced corroded carbon steel alternatives, reducing maintenance outages by 30%. Their resistance to salt spray ensured reliable performance during hurricane season, preventing costly power disruptions for coastal communities.
