Below is a list of similarities and differences between the two grades. Previous tab Next tab.

As for the torque, that is not a14 easy question since torque is notoriously unpredictable. They are work-hardened to a high degree, making them stronger and better-suited for mechanically straining applications, like vehicle suspension systems.

ASTM A – Portland Bolt

However, the minimum proofload for 2HM nuts is ksi, so it should have sufficient strength to work properly with B7 bolts. Testing The main difference between 2H and 2HM nuts is in the testing. This is the most common grade used in automotive applications. Grade 2 material is highly workable, and forms the bulk of steel grade fasteners. Grade 5 steels are produced from unalloyed medium carbon groups, such as typeand are usually work-hardened to improve their strength.


This is a low carbon category that features the least expensive, but also least durable, types of steel. Their mechanical strength ranges from approximately 50 ksi kilo-pound per square inch up to ksi in a finished product.

We export fasteners to: These steels are typically medium carbon alloys, gradde as types and Hastelloy is a registered trademark of Haynes International. Carbon steel fasteners is the most common type of steel used in fastener production. Ruben- B7M y 2HM tienen menor resistencia y deben marcarse en consecuencia.
