ASTM A194 Grade 2H Fasteners
Leave this field empty. Carbon steel grase is the most common type of steel used in fastener production. Previous tab Next tab. Search Products Search for: While not showing all of the sizes, this is a representative sample.
Grade 5 steels are produced from unalloyed medium carbon groups, such as typeand are usually work-hardened to improve their strength.
Special Fasteners for Special Projects Testing The main difference between 2H and 2HM nuts is in the testing. 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.
ASTM A – Portland Bolt
Grade 2H nuts have a higher proof load requirement. 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?
Hardox is registered trademark of SSAB. These nuts are intended for high-pressure or high-temperature service, or both. No products in the cart. These steels are typically medium carbon alloys, such atsm types and Proof Load, lbf Stress Area in.

As for the torque, that is not an easy question since torque is notoriously unpredictable. Protect legibility of markings Minimize exterior dimensional changes Maintain thread fit Chemical Composition Both 2H and 2HM nuts have the same chemical composition.
This is the most common grade used in automotive applications. However, the minimum proofload for 2HM nuts is ksi, so it should have sufficient strength to work properly with B7 bolts. Material properties for these grades include:. Below is a list of similarities and differences between the two grades. 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 grqde. PM Metal provides guidelines with respect to fastener patterns and spacing to prevent this problem.
Their graee strength ranges from approximately 50 ksi kilo-pound per square inch up to ksi in a finished product. They are asttm to a high degree, making them stronger and better-suited for mechanically straining applications, like vehicle suspension systems.
