Bolt designation
Bolt designation
(OP)
I am working on a project where the design criteria provided states the following:
Anchor bolt: strength class 5.6
Nuts: strength class 8
Washers: strength class 100hv
I would like to know the strength of each of these and the meaning of each designation.
And yes, I did an internet (unsuccessful) internet search before posting. This is for a metric project. It seems that the number indicates some sort of material strength.
Any ideas?
