Astm A Grade 2H Heavy Hex Nuts From TorqBolt

The tests for 2HM ast must also take into consideration 3 additional things during testing: These nuts are intended for high-pressure or high-temperature service, or both. 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.

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


Hastelloy is a registered trademark of Haynes International. Special Fasteners for Special Projects 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.

Their mechanical strength ranges from approximately 50 ksi kilo-pound per square inch up to ksi in a finished product. If the bolts is B7 and the nuts grqde is 2HM in term of quality and strength of materials during bolt torquing have no effect or any significants regarding this matter? Below is a list of similarities and differences between the two grades.

They are work-hardened to a high degree, making them stronger and better-suited for mechanically straining applications, like vehicle suspension systems. We export fasteners to: The tests for 2HM nuts must also take into consideration 3 additional things during testing:.

Special department for odd size fasteners! Grade 2 material is highly workable, and forms the bulk of steel grade fasteners. As for the torque, that is not an easy question since torque is notoriously unpredictable.

Proof Load, lbf Stress Area in. These steels are typically medium carbon alloys, such as types and Bolts with flattened Panhead with Allen. PM Metal provides guidelines with respect to fastener patterns and spacing to prevent this problem. Grade 5 steels are produced from unalloyed medium carbon groups, such as typeand are usually work-hardened to improve their strength. No products in the cart.
