  2. Unified Thread Standard - Wikipedia

    en.wikipedia.org/wiki/Unified_Thread_Standard

    The minor diameter D min (also known as the root diameter) is the diameter of the screw measured from the inner edge of the threads. The major diameter may be slightly different from the shank diameter, which is the diameter of the unthreaded part of the screw. The diameters are sometimes given approximately in fractions of an inch (e.g. the ...

    Because only 5 ⁄ 8 of this height is cut, the difference between major and minor diameters is 5 ⁄ 4 × 0.8660 × P = 1.0825 × P, so the tap drill size can be approximated by subtracting the thread pitch from the major diameter. In an external (male) thread (e.g. on a bolt), the major diameter D maj and the minor diameter D min define ...

    en.wikipedia.org/wiki/Screw_thread

    The nominal diameter of Metric (e.g. M8) and Unified (e.g. 5 ⁄ 16 in) threads is the theoretical major diameter of the male thread, which is truncated (diametrically) by 0.866 ⁄ 4 of the pitch from the dimension over the tips of the "fundamental" (sharp

    The major diameter is given by 6p 1.2, [4]: 12 rounded to two significant figures in mm and the hex head size (across the flats) is 1.75 times the major diameter. BA sizes are specified by the following British Standards: BS 57:1951 — B.A. screws, bolts and nuts

  7. British Standard Whitworth - Wikipedia

    en.wikipedia.org/wiki/British_Standard_Whitworth

    The thread pitch increases with diameter in steps specified on a chart. The Whitworth thread system was later to be adopted as a British Standard to become British Standard Whitworth (BSW). An example of the use of the Whitworth thread are the Royal Navy's Crimean War gunboats.

  8. ISO 965 - Wikipedia

    en.wikipedia.org/wiki/ISO_965

    ISO 965 (ISO general purpose metric screw thread—tolerances) is an International Organization for Standardization (ISO) standard for metric screw thread tolerances. [1] It specifies the basic profile for ISO general purpose metric screw threads (M) conforming to ISO 261 .

  9. Trapezoidal thread form - Wikipedia

    en.wikipedia.org/wiki/Trapezoidal_thread_form

    The maximum diameter (within tolerance) at the crest of the external threads (called the max. major diameter of external thread) is that of the basic thread form and equals the "nominal diameter", D, stated in the screw's designation.
