Sstm department for odd size fasteners! However, the minimum proofload for 2HM nuts is ksi, so it should have sufficient strength to work properly with B7 bolts.

ASTM A194 Grade 2H vs. 2HM

This is a low carbon category that features the least expensive, but also least durable, types of steel. Grades 2, 5, and 8 are typically the standard for carbon steel screws and bolts, with alloyed gade steel being a higher-end variation on these metals.
