This is the most common grade used in automotive applications. Protect legibility of markings Minimize exterior dimensional changes Maintain thread fit Chemical Composition Both 2H and 2HM nuts have the same chemical composition.

grzde However, the minimum proofload for 2HM nuts is ksi, so it should have sufficient strength to work properly with B7 bolts. Grades 2, 5, and 8 are typically the standard for carbon steel screws and bolts, with alloyed carbon steel being a higher-end variation on these metals.

The main difference between 2H and 2HM nuts is in the testing. The tests for 2HM nuts must also take into consideration 3 additional things during testing: Hex head fasteners, Non-standard fasteners, high strength fasteners, socket head fasteners, wall fasteners, brass fasteners, mechanical fasteners, aluminium fasteners, concrete fasteners, railway fasteners, motorcycle fasteners, bronze fasteners, self-clinching fasteners, self-locking fasteners, sheet metal fasteners, panel fasteners, aluminium bronze fasteners, silicon bronze fasteners, torx fasteners, phosphor bronze fasteners.
