A thread is a groove that in the case of fasteners is typically of a vee form. Enlarging a section of a thread it can be observed as a series of ridges and hollows. Specific names are given to parts of the thread. The crest is the topmost section of the thread. The root is the bottom of the thread. The thread flanks lie between the roots and crest of the threads. The major diameter of a thread is, for an external thread, the diameter over the crests of the thread. For an internal thread it is the diameter over the thread roots. The pitch diameter cannot be directly measured since there is no marking or indication on the thread to measure. To explain the pitch diameter, it is first necessary to understand what the pitch is.   For inch threads, the pitch is defined as the number of threads per inch - or tpi. With metric threads the pitch is directly specified. The pitch diameter is the diameter on the thread that the space between the threads is equal to the spac...
