Hexagonal Nut Guy Clamp is a core component used to anchor steel strands on high-voltage transmission lines. Handan Jinmai uses high-precision cold forging technology to ensure that the product maintains structural integrity under extreme climate and mechanical stress, and prevents safety accidents caused by loose wires. It is suitable for scenarios such as substations, towers, and communication base stations, and is compatible with all types of standard steel strands (Guy Wire).
✅ Triple safety protection
Anti-loosening design: Hexagonal nut with serrated lock washer, torque retention rate ≥95% under vibration environment
Anti-corrosion coating: Hot-dip galvanized layer (≥86μm) passed ISO 1461 salt spray test, service life exceeds 30 years
Non-destructive clamping: V-shaped crimping tooth groove design, protects the zinc layer on the surface of steel strand when tightening
✅ Engineering optimization design
One-piece U-bolt, tensile strength of 1,200MPa
Streamlined pressure plate reduces wind vibration and reduces fatigue fracture risk by 60%
Visual torque indicator groove for easy construction quality inspection
✅ Global adaptability
Compliant with IEEE 524/ANSI C135 standards
Supports 8mm-22mm diameter steel strand (customizable to 32mm)
Handan Jinmai implements military-grade quality control process:
1. Raw material screening: Baosteel BST500B high-strength boron steel bar material is used
2. Cold forging: 2500-ton hydraulic press precision forging, 100% maintenance of metal flow line integrity
3. Thread processing: CNC thread rolling machine forms UNRC 2A grade thread, accuracy ±0.01mm
4. Surface treatment: Automated galvanizing line, real-time monitoring of zinc layer thickness
5. Load test: Sampling for 3 times working load (SWL) destructive test
