American Standard hexagonal drill screws (also known as hexagonal head self-tapping screws) are usually divided into two sizes: coarse and fine. The difference between the two sizes is the spacing and depth of the threads. Coarse threads have a large thread spacing and deep threads and are suitable for looser materials such as wood. They are commonly used in construction, furniture manufacturing, carpentry, and other applications where fixation in loose materials is required.
