What Are the Different Grades of Bolts? Hunker

A bolt head with three raised dashes in a radial pattern marks an SAE grade 5 bolt of tempered medium carbon steel with a tensile strength of at least 105,000 pounds per square inch. The strongest commercial quality bolt is grade 8, marked by six raised dashes; its medium carbon alloy steel has been quenched and tempered to achieve a tensile Fastener Identi cation MarkingsASTM, SAE, ISOFastener Identi cation MarkingsASTM, SAE, ISO Identi cation Grade Mark Speci cation Fastener Description Material Nominal Size Range (in.)
