  3. British Standard Whitworth - Wikipedia

    en.wikipedia.org/wiki/British_Standard_Whitworth

    The Unified thread angle is 60° and has flattened crests (Whitworth crests are rounded). From 14 in up to 1 + 1 ⁄ 2 in, thread pitch is the same in both systems except that the thread pitch for the 1 ⁄ 2 in bolt is 12 threads per inch (tpi) in BSW versus 13 tpi in the UNC.

  5. Unified Thread Standard - Wikipedia

    en.wikipedia.org/wiki/Unified_Thread_Standard

    The standard thread pitch is approximately ⁠ 1 / 4 ⁠ of the major diameter. The thread form is slightly modified to increase the minor diameter, and thus the strength of screws and taps. The major diameter still extends to within ⁠ 1 / 8 ⁠ H of the theoretical sharp V, but the total depth of the thread is reduced 4% from ⁠ 5 / 8 ⁠ H ...

    A diagram of an ISO metric or Unified thread, showing dimensions relative to the pitch (P) and thread height (H). Due to different standards, ISO and UTS share the same geometry, but not absolute dimensions. Also shown is the location rounding permissible in internal (dark grey, top) and external (light grey, bottom) threads. Key. P: Pitch; H ...
