Hexagonal aluminum alloy nut - Precision CNC mechanical part - Through nut

Practical Products

CNC Production & Processing Features

• Optional high corrosion resistance and high conductivity: Copper alloy nuts provide improved conductivity, while stainless steel nuts deliver enhanced corrosion resistance.
• CNC customization available for flange faces, anti-loosening slots, and multi-step nuts to meet assembly requirements of base stations and servers.
• Surface treatments including hot-dip galvanizing and Dacromet coating to improve salt spray and humidity resistance in outdoor environments.
• Excellent dimensional consistency and stable internal thread precision, suitable for mass assembly and automated equipment installation.

Common CNC Machining Issues & Key Points

• Anti-corrosion Treatment Issues

   

  Coating peeling, uneven thickness, and internal thread clogging often occur after hot-dip galvanizing or Dacromet coating. Ensure surfaces are free of oil and burrs before processing, strictly control coating processes, and clean residual coating from internal threads after processing to guarantee smooth threading.
   
• Multi-step Machining Issues

   

  Multi-step nuts for cabinet guide rails and antenna mounts are prone to coaxiality deviation and misalignment between internal threads and steps, causing assembly jams. Use one-time clamping machining, control dimensional tolerances and coaxiality of each step to avoid out-of-tolerance defects.
   
• Anti-loosening Structure Machining Issues

   

  Dimensional deviations in anti-loosening slots prevent proper fitting of anti-loosening washers and reduce anti-loosening performance. Precisely machine slot dimensions to ensure tight fitting of washers, and conduct anti-loosening performance tests after processing to prevent loosening in long-term use.
   
• Outdoor Adaptability Issues

   

  Base station nuts must withstand high and low temperature variations. Use weather-resistant materials and control heat treatment processes to avoid brittle cracking at low temperatures and deformation at high temperatures, ensuring stable internal thread precision.
