Designed for precision connections in tower structures, these mini metal fittings include nuts, bolts, washers, and brackets for micro-load applications. Crafted from high-grade alloy steel or stainless steel, they ensure reliable performance in tight spaces where traditional components are impractical.
Micro-Engineering Excellence
Miniature thread sizes (M4-M10) with ISO metric precision (6g/6H tolerance), tested for torque retention at 80% of proof load.
Surface treatments: zinc-nickel plating (for marine use, 1,500-hour salt-spray resistance) or black oxide (for aesthetic concealment in interior components).
Material Versatility
304 stainless steel options (ASTM A240) for chloride-resistant environments, the 316L variant (ASTM A240) for offshore installations with high salinity.
Titanium alloy fittings (Ti-6Al-4V) for weight-sensitive applications, reducing component mass by 40% without compromising strength (yield strength: 830MPa).
Ergonomic Design
Hexagon socket heads with anti-slip grooves, enabling tool-free hand tightening in confined spaces (torque range: 0.5-5N·m).
Chamfered edges to prevent damage to protective coatings during installation.
Tower Monitoring Systems: Securing vibration sensors and strain gauges in 2MW-3MW turbines, with IP67-rated weatherproof seals.
Solar Tracker Towers: Micro-connections for azimuth and elevation adjustment mechanisms, compatible with automated lubrication systems.
Telecom Antenna Mounts: Lightweight fittings for securing 5G antennas on lattice towers, compliant with IEC 62305-3 lightning protection standards.
Precision Manufacturing: Utilize Swiss-type CNC lathes for ±0.01mm dimensional accuracy, ideal for aerospace-grade wind tower sub-components.
Rapid Prototyping: 3D-printed prototypes available within 72 hours for custom geometries, supported by a 100+ million component annual production capacity.
