WebMetric Grades The strength grade of a metric bolt, known as its property class, consists of two numbers separated by a dot. The property class is expressed in raised or depressed numerals on top or on the side of the bolt head, according to rules set by the International Standards Organization. WebGrade 8. With a tensile strength of 150,000 pounds per square inch, grade 8 hex cap screws are stronger than grade 5. This grade is heated similar to grade 5, but they are fully heat treated versus case hardened. Their strength makes them good candidates for tractor fabrication, suspension applications and other high demand fastening applications.
