As I recall, bolts without markings on the heads are grade 2, bolts with
three lines are grade 5, with bolts that have 6 lines are grade 8. Grade 2
is general purpose, grade 5 is medium strength with grade 8 being the
strongest. Bolt usage is complex however, and use of a grade 8 bolt where a
compliant one, such as a grade 2 or 5, is called for might be dangerous.
