More difference between UNF thread and UNC thread are as following 1)The UNF threads have smaller helix angle and better tightness, and it is more conducive to the selflocking of the thread Therefore, it's not that easy to be loosen compared with UNC threads It is generally used for thinwalled parts and parts with higher anti vibration1/4" Threaded Studs (UNC Thread) Threaded studs are available in 1/4" and 3/8"16 thread diameters with a variety of external thread and shank lengths for use in concrete, concrete over steel deck, concrete masonry walls and steelRead the second number to find the number of threads per inch It can also be called the thread pitch Metal screws tend to have more threads per inch than wood screws, for instance Coarse screws also have a larger pitch measurement than fine screws A #440 UNC3A x 5 screw has 40 threads per inch
