Metric Fastener Grades & Strengths Explained!! (Class 4.6, 8.8, 10.9, & 12.9) 

Those are megapascals (MPa) not millipascals...

Great video man, very helpful!

Why we use 8.8 bolt over 10.9 and 12.9 in iron and steel making industries?

Just an FYI; its megapascal not millipascal. if it was millipascal it would be 1/1000 of a pascal in lieu of 1000000 pascals (1Mpa).. thanks

i'm doing a DIY major maintenance to my hyundai azera & i want my work to be pro. so i'm going to fasten with the proper torque by a meteric fasteners table providing torque for every diameter. the problem is this metric table is asking for the class\garde of the fasteners & the fasteners is only having the number of the diameter on it only! so how to know the grade? is it by the color? or should i do the lower torque for the lower grade to be in the safe side? but i'm afraid it wont tight things properly!

Good morning, I am having a really had time finding a 10.9 bolt of the size I need. Can I use a grade 8 bolt for a car suspension application?

Can we have bolts of different diameters but same gade
