  • Lead screws in 3D printers
  • Motion control systems
  • Manufacturing jigs and fixtures
  • Conveyor systems and linear actuators

6. Square Thread Nuts

Square thread nuts have a square-shaped profile with straight-sided threads, offering high efficiency in translating rotational motion into linear motion. These nuts provide excellent precision and repeatability in positioning applications, making them well-suited for additive manufacturing processes requiring accurate alignment and controlled movement.

Applications:

  • CNC machine tool slides
  • Robotics and automation equipment
  • Positioning stages and actuators
  • Optical and laboratory instruments

By exploring the diverse range of nut thread types and their applications in additive manufacturing, designers and engineers can select the most suitable nut thread type to meet specific requirements, enhance performance, and optimize the functionality of printed parts and assemblies.
