    how to calculate tensile strength of bolt.
    Property Class is a designation system which is used to defines the strength of metric fasteners i.e Bolts nuts as per ISO898- part 1. The metric fasteners are designated by a symbol comprised of 2 numbers, separated by a decimal. For example 4.6 and 8.8. The property class is normally stamped on the head of the bolt.
    The first digit of bolt grade represents (1/100) th part of the nominal tensile strength or proof load stress in mega pascals. For example, a bolt with property class 4.6 have nominal tensile strength equal to 4 x 100 = 400 MPa.

    Hi there, may I know what's the different between Grade A,B as specified in ISO 4014 & Grade C specified in ISO 4016.
    How do we justify when compare to Bolt Class 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 10.9?
    Can I say that ISO 4014 only cover up to Bolt Class 5.8?
    6.8, 8.8 will be under ISO 4016?
    And how about 10.9?
    Thanks

    Thank you, so the equation of 24 is 12... of spannar or wrench.
    the biggest bolt is 24 diameter (nut),commonly nuts and screws are use 12.

    A SAE (Standard) bolts thread is measured by the distance between the threads not how many per inch?

    • @paul-ld9vh
      @paul-ld9vh Рік тому +1

      SAE bolts are expressed in bolt thickness and then threads per inch.
      Example---1/4 -20 means that the bolt is 1/4 of an inch thick and has 20 threads per inch. The other dimension would be length, which is also expressed in inches.

    The grade of a bolt says what the yield strength the bolt has. true or false?

    • @technoworks.
      @technoworks.  2 роки тому +1

      Not only yield strength or proof strength but it also tells tensile strength

    It's come in which subject please tell me. 12.9 bolt yeild strength is 900 as per your video but isro exam take ans is 1080 so i want to proof for rise objections. Pls

    • @technoworks.
      @technoworks.  2 роки тому +3

      12.9 means 1200 MPA is tensile strength and yield strength is 90% of 1200 Mpa= 1080 Mpas

    Tensile stress = proof load
    then
    Yield strength < Prof load

      Pa (Pascal) is pressure 1Pa = 1 N/m2 ( Newton/ m2) 1MPa = 1million Pascal . 1bar (approx 1kgf/cm2 = barometric pressure) 1bar = 100 kPa = 100 kN/m2
