Excuse me, I'm a bit confused by your question. Are you referring to bolts in the context of hardware and fasteners, or perhaps in a different context entirely? If you're talking about bolts used in construction or mechanical engineering, there isn't typically a grading system based on school levels like grades 1-12. However, bolts are often classified based on their strength, material, and other factors.
If you're looking for bolts with a certain level of strength or durability, it might be more helpful to specify the type of bolt you're interested in, such as high-strength bolts or stainless steel bolts. Can you provide more context for your question so I can give you a more accurate answer?
