In self drilling anchor bolts (SDA) markets, there might be some people who think thatthe anchor quality is related to the grade of material strength.
But this is not true.
The grade of material strength is based on its yield strength. However, for the Grade of Product Quality, the key index should be its ductility (i.e. the values of Agt and Rm/Rp0.2, according to Eurocode EC2↓↓↓).
