Bolt Grade Identification
Bolt grade markings are used to categorize bolts according to the bolt material, man-
ufacturing process, and mechanical properties. The grade of the bolt is stamped on the
head of the bolt.
US SAE bolts
: The bolt grade markings are determined by the number of the lines stamped
on the head of the bolt. The number of lines is always two less than the grade of the bolt.
Count the lines, add two, and you can determine the grade of the bolt.
