What is the strongest bolt grade

different grades of bolts?

grades of bolt strength.

how to calculate bolt strength.

how to calculate bolt proof strength.

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

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

Are there grade for nuts and not for bolts?

Please explain about its material can be use and it's properties

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.

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

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

This is only ISO standard. Plz explain SAE and ANSI standard

Tensile stress = proof load
then

Yield strength < Prof load


Please explain relation between yield strength and proof load

1 MPA = 10Bars
400MPA = 4000Bars
240MPA = 2400Bars

maybe just old ears but even pausing regularly the voice over was not easily understood- I'd like to hear another voice narrating- maybe a human one?
