What is Understanding Bolt Markings and Torque about?

The marks on a bolt head indicate the manufacturer and grade/material properties. The manufacturer mark identifies the company and the grade mark identifies the material standard, such as "8.8" for a property class. These marks are usually on the top of the bolt head and can be raised or depressed, with raised being preferred.
