Triangular eye bolts are core load-bearing connectors in power transmission systems, optical cable installations, and communication infrastructure. They are designed for high-altitude suspension, tension adjustment, and equipment fixation. Handan Jinmai Fastener Manufacturing Co., Ltd. relies on its own factory advantages and uses high-strength alloy steel and advanced anti-corrosion technology to create a customized triangular eye bolt series suitable for extreme environments. The product has passed the National Electric Power Industry Quality Inspection Center certification (GB/T 2314 standard) and can perfectly adapt to OPGW optical cable fittings, ADSS suspension clamps, and power tower structures.
1. Triple safety design
Triangular closed loop structure: One-piece eye ring design avoids the stress concentration problem of traditional round eye rings and increases tensile strength by 30% (maximum load up to 70kN).
Hot-dip galvanized layer: ≥86μm zinc layer thickness (in line with ISO 1461 standard), passed the salt spray test for 1000 hours, and is suitable for high corrosion environments such as coastal areas and industrial areas.
Anti-loosening thread technology: Precision rolled threads with anti-slip teeth ensure no loosening and falling risks under long-term vibration conditions.
2. Flexible customization service
Supports deep customization of materials (stainless steel 304/316, alloy steel), sizes (M12-M36), load levels (8.8 to 12.9) and surface treatments (Dacromet, epoxy coating).
1. Precision forging uses a 630T friction press to perform closed die forging on alloy steel billets to eliminate internal pores and improve the continuity of metal flow lines.
2. CNC machining controls the thread tolerance (6g grade) through CNC lathe machining, and cooperates with laser detection to ensure that the concentricity between the eye ring and the screw is ≤0.05mm.
3. Double anti-corrosion treatment first undergoes alkaline degreasing → acid pickling activation → plating agent infiltration, then 450℃ high temperature hot dip galvanizing, and finally passivation sealing to achieve triple protection.
