The noticeable difference between National Coarse (NC) and National Fine (NF) threading is the number of threads per inch.

National Course (NC) is the most common general fastener thread; the fit is deeper and is more versatile in its application. With fewer threads, it is easier to apply and easier to remove. Coarse threading also handles manufacturing and plating better than Fine threading due to it having greater tolerances.

However, National Fine (NF) threads are not as deep as National Course (NC) threads and this larger minor diameter allows for better load–carrying ability. The fit is more specific with finer tension adjustment and tighter tolerances. Finer pitch threads are mostly used in applications where safety or where loosening due to vibration or shock would be an issue.
