What does the term 'crest' refer to in threading?

  1. The lowest point of the thread

  2. The highest point of the thread

  3. The angle of the thread

  4. The root surface of the thread

The correct answer is: The highest point of the thread

The term 'crest' in threading specifically refers to the highest point of the thread. In the context of screw threads, the crest is crucial because it is the part that comes into contact with the opposing thread when two threaded components are engaged. Understanding the crest helps in determining how threads interact with each other, affecting their load-bearing capacity and overall performance. This knowledge is essential for ensuring the correct fit and function in mechanical assemblies where threaded connections are critical.
