Sep 11, 2023 · There are two main grading systems for bolts: the SAE system and the metric system. SAE system: The SAE system is used in the United States and Canada. The most common SAE bolt grades are 2, 5, 8, and 10. Grade 2: The weakest grade. It is typically used for light-duty applications.
Three Systems of Bolt Grades. There are three main systems of bolt grades: SAE, ASTM, and ISO. SAE (Society of Automotive Engineers) grades bolts according to their strength, ranging from grade 2 to grade 8. Grade 2 is the weakest, and grade 8 is the strongest.
This chart helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength and hardness of common grade bolts. Please note the bolt heads may also include the manufacturer's identification stamp, especially with high strength bolts.
