Bolt Head Grade Markings. 38 rows hex bolt identification, markings and strength chart. 24 rows this chart helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength. Grade 2, 5, and 8 are the most common grades of fasteners according to the society of automotive engineers standard. The higher the grade is, the stronger the material that makes up the fastener. Hardnesses are brinell hardness numbers. the grades are typically indicated by markings engraved on top of the bolt head, which may show up as raised numbers or dashes. Additonal information on bolts is located at the bottom of the. bolts meeting sae j429 standards have radial lines engraved on the bolt head. properties shown are those of coarse 8‐thread heavy hex nuts. three radial lines will indicate an sae grade 5 fastener, while six radial lines will indicate an sae grade 8 fastener. The maximum load in tension (pulling apart) which a material can withstand before. These designations assist engineers in choosing bolts appropriate for specific applications.
