Technically you can't buy a Grade 8 bolt in a metric size. I suggest you look for Class 8.8 minimum but think you would be better served with a Class 10.9 bolt. You probably will have to go to a real hardware store or a bolt supplier.
Belmetric is a quality online
business that has a wide range of metric bolts
So what grade would you compare the CURT bolt to?
Can't tell what the marking is on the bolt head in picture. IF 8.8 -this is a class 8.8 bolt. Class 10.9 would be marked "10.9".
