Three Wire Thread Measuring Sets are precision instruments used for measuring the pitch diameter of threaded components, particularly external threads. This method is based on the principle of using three wires of known diameter placed in the grooves of the thread to determine the effective diameter.

Advantages

  • Accuracy : Provides highly accurate measurements of pitch diameter, essential for ensuring proper thread engagement and performance.
  • Versatility : Can be used for a variety of thread types and sizes, depending on the wire diameters and thread standards.
  • Non-Destructive Testing : Allows for measurement without damaging the threads being inspected.

Applications

  • Used in industries such as automotive, aerospace, and machinery manufacturing to verify the accuracy of threaded parts, including screws, bolts, and nuts.
  • Ideal for quality control inspections during manufacturing processes to ensure compliance with thread specifications.
  • Useful in tool and die shops for checking the accuracy of threading tools.
