Looking at the head of the bolt if it has 2 hash marks it's a grade 3 ,3 marks makes it a grade 5, 5 marks makes it a grade 7, and 8 marks makes it a grade 8( 8 is usually yellow cad color) . Some bolts might have a number on the head (usually grade 8 bolts) this also indicates their grade. I imagine the DCPD script bolts are a grade 5 or 7. Some of the script bolts I took off my winch bumpers were bent, a grade 8 bolt will bend very little before it snaps(the higher the hardness the more rigid the bolt) Hope some of this helps,Bill.
