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.

Brilliant explanation. Thank you.
Simple and effective info
Obviously this is only for Metric Bolts.
So First Number is Tensile Strength (Max Force at when the bolt will “BREAK”)
And Second Number, after the Point, is a Yield Strength (Max force at which the bolt will start to “DEFORM”)
So first number is “Breaking” force and second is a Percentage of the first number at which force the bolt will start to “Deform”.
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
Thanks for the information
Nice❤
جیتی رھو بہت اعلی بہت خوب
Stay alive, very high, very good
Best explanation ever 🎉🎉
Thanks for information
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.
good information.Thanks
Thanks for this.
So the type of colors difference for bolt is just for look and personal liking standard only??? So what type are bolts are for car???
At last I got my answers here ☺
Me too

Very helpful video.🙏🏼🙏🏼👍👍
instablaster.
thanks alot
Perfect. Thanks!
nice ..
Thanks
Are there grade for nuts and not for bolts?
Tensile stress = proof load
then
Yield strength < Prof load
Please explain relation between yield strength and proof load

A SAE (Standard) bolts thread is measured by the distance between the threads not how many per inch?
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.
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?
Thank you for your comment... you saved me valuable time... I skipped the video and blocked the channel.
The grade of a bolt says what the yield strength the bolt has. true or false?
Not only yield strength or proof strength but it also tells tensile strength
Please explain about its material can be use and it's properties

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
12.9 means 1200 MPA is tensile strength and yield strength is 90% of 1200 Mpa= 1080 Mpas
@@technoworks. i am doing wrong in multiplication so my ans is wrong

Why dont they write the size on it aswel ! 🤯

1 MPA = 10Bars
400MPA = 4000Bars
240MPA = 2400Bars
My bolt number is 11?
🔥🔥🔥🔥🔥
This is only ISO standard. Plz explain SAE and ANSI standard
I have been a dumb
what is Mpa actually??
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
