What term describes the top surface joining adjacent sides of a thread?

Flank
Root
Crest
Shoulder

The correct answer is: Crest

The term that describes the top surface joining adjacent sides of a thread is known as the crest. In screw threads, the crest is the highest point or the surface that forms the peak of the thread. This is significant because the crest is critical for defining the dimensions and fit of threaded fasteners. It affects how the screws or bolts engage with corresponding threaded holes or nuts, influencing the strength and stability of the connection. Understanding the geometry of threads, including concepts like the crest, is essential in millwright practices, particularly for ensuring proper alignment and load distribution in mechanical assemblies.
