  2. ISO metric screw thread - Wikipedia

    en.wikipedia.org/wiki/ISO_metric_screw_thread

    A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ...

  3. List of drill and tap sizes - Wikipedia

    en.wikipedia.org/wiki/List_of_drill_and_tap_sizes

    The drill sizes that are near this are 6.3 mm (90%), 1 ⁄ 4 in (90.7%), 6.4 mm (91.4%), and 6.5 mm (92.9%); any of these will work well. For metric V threads, major minus pitch yields a good tap drill diameter. Example (metric, coarse): For M7.0 × 1.0, 7.0 − 1.0 = 6.0; Example (metric, fine): For M7.0 × 0.5, 7.0 − 0.5 = 6.5

  4. List of screw drives - Wikipedia

    en.wikipedia.org/wiki/List_of_screw_drives

    In Japan, the male sizes are often designated as DTC-20, DTC-27, DTC-40 (discontinued) and DTC-45 corresponding to a respective screw head size of 3.2 mm, 4.6 mm, 6.4 mm and 7.7 mm; with the size of the screw measured across the widest portion of the mating part of the head. The most common sizes in use for consumer electronics are DTC-20 and ...

  5. Birmingham gauge - Wikipedia

    en.wikipedia.org/wiki/Birmingham_gauge

    The gauge starts at the lowest gauge number of 5Ø or 00000, corresponding to the largest size of 0.500 inches (12.7 mm), and runs to the highest gauge number of 36, corresponding to the smallest size of 0.004 inches (0.10 mm).

  6. Hex key - Wikipedia

    en.wikipedia.org/wiki/Hex_key

    The idea of a hex socket screw drive was probably conceived as early as the 1860s to the 1890s, but such screws were probably not manufactured until around 1910. Rybczynski (2000) describes a flurry of patents for alternative drive types in the 1860s to the 1890s in the U.S., [2] which are confirmed to include internal-wrenching square and triangle types (that is, square and triangular sockets ...

  7. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The millimetre (SI symbol: mm) is a unit of length in the metric system equal to 10 −3 metres (⁠ 1 / 1 000 ⁠ m = 0.001 m). To help compare different orders of magnitude , this section lists lengths between 10 −3 m and 10 −2 m (1 mm and 1 cm).

  8. Unit of volume - Wikipedia

    en.wikipedia.org/wiki/Unit_of_volume

    6 volumetric measures from the mens ponderia in Pompeii, a municipal institution for the control of weights and measures (79 A. D.). A unit of volume is a unit of measurement for measuring volume or capacity, the extent of an object or space in three dimensions.

  9. Fracture toughness - Wikipedia

    en.wikipedia.org/wiki/Fracture_toughness

    In addition to this thickness calculation, test specifications have several other requirements that must be met (such as the size of the shear lips) before a test can be said to have resulted in a K IC value. When a test fails to meet the thickness and other plain-strain requirements, the fracture toughness value produced is given the ...
