However projects with eastern origin are possible on request.
Below is a list of similarities and differences between the two grades. Testing The main difference between 2H and 2HM nuts is in the testing. Grade 5 steels are produced from unalloyed medium carbon groups, such as typeand are usually work-hardened to improve their strength.
Sanicro 28 is a registered trademark of Sandvik AB.
Grade 2H nuts have a higher proof load requirement. The main difference between 2H and 2HM nuts is in the testing.
If the bolts is B7 and the nuts installed is 2HM in term of quality and strength of materials during bolt torquing have no effect or any significants regarding this matter? However, the minimum proofload for 2HM nuts is ksi, so it should have sufficient strength to work properly with B7 bolts. The tests for 2HM nuts must also take into consideration 3 additional things during testing: Grade 2 material is highly workable, and forms the bulk of steel grade fasteners.

Material properties for these grades include:. As for the torque, that is not an easy question since torque is notoriously unpredictable. Protect legibility of markings Minimize exterior dimensional changes Qstm thread fit Chemical Composition Both 2H and 2HM nuts have the same chemical composition.
Search Products Search for: While not showing all of the sizes, this is a representative sample. This is a low carbon category that features the least expensive, but also least durable, types of steel. We export fasteners to: This is the most 2u grade used in automotive applications.

No products in the cart. Your email address will not be published. The tests for 2HM nuts must also take into consideration 3 additional things during testing:. Carbon steel fasteners is the most common type of steel used in fastener production. They are work-hardened to a high degree, making them stronger and better-suited for mechanically straining applications, like vehicle suspension systems. 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.
