  3. List of drill and tap sizes - Wikipedia

    en.wikipedia.org/wiki/List_of_drill_and_tap_sizes

    Example (inch, coarse): For size 7 ⁄ 16 (this is the diameter of the intended screw in fraction form)-14 (this is the number of threads per inch; 14 is considered coarse), 0.437 in × 0.85 = 0.371 in. Therefore, a size 7 ⁄ 16 screw (7 ⁄ 16 ≈ 0.437) with 14 threads per inch (coarse) needs a tap drill with a diameter of about 0.371 inches.

    In reality, the 40 nominal bore part bears little resemblance to the size and dimensions of the U-bolt. As U-bolts are now being used by a much wider audience to clamp any kind of tubing / round bar, then a more convenient measurement system needs to be used. U-bolts are used to hold rebar cages [1] and overhead road signs. [2]

    ACI Code 7.10.4.2: For cast-in-place construction, size of spirals shall not be less than 3/8 in. diameter. ACI Code 7.10.4.3: Clear spacing between spirals shall not exceed 3 in., nor be less than 1in. Section 10.9.3 adds an additional lower limit to the amount of spiral reinforcement via the volumetric spiral reinforcement ratio ρ s.

    en.wikipedia.org/wiki/Tie_rod

    The rebar used in reinforced concrete is not referred to as a "tie rod", but it essentially performs some of the same tension-force-counteracting purposes that tie rods perform. In automobiles, the tie rods are part of the steering mechanism. They differ from the archetypal tie rod by both pushing and pulling (operating in both tension and ...

    Machine screws with different thread diameters Hex key set with metric sizes from 2 mm to 10 mm according to sizes for use with ISO 262 screw sizes (except 3.5 mm for M6 internal set screw) For each size bolt or screw and type of head, there is a corresponding size driver prescribed by various ISO standards, including:

  8. Rebar detailing - Wikipedia

    en.wikipedia.org/wiki/Rebar_detailing

    Rebar detailing is the discipline of preparing 'shop/placing' or 'fabrication' drawings or shop drawings of steel reinforcement for construction. Engineers prepare 'design drawings' that develop required strengths by applying rebar size, spacing, location, and lap of steel .

    The NMRA published alternative, more accurate and realistic standards for track and wheels sheet in S-1.1 These model railway standards are based on the full size prototype standards and the scale model operational reliability is therefore reduced in comparison to the models conforming to the normal NMRA standards.
