For the UNF version, the same 1/4″ bolt will have a finer thread with 28 threads per inch, requiring a slightly larger tap drill size of 5.50 mm, and the pitch between threads will …, Pitch: By default, the pitch is given in TPI. For example, 1/4-20 means a thread with a pitch of 20 TPI (1/20=0.05″). It is also allowed to denote the pitch by distance. For example, 1/4-0.05P means a thread with a pitch of 0.05″ (same as 20 TPI). Series: In most cases, the series will be UNC, UNF, or UNEF (Coarse, Fine, or Extra fine pitch)., Typically, metric thread callouts also come with the thread pitch, such that an M6 × 1 threaded bolt has a basic major diameter of 6 mm and a thread pitch of 1 mm. When purchasing a threaded fastener, make sure you have both the diameter and the thread pitch. Without one of those measurements, you could buy the wrong-sized hardware., Tennessee.
