They are work-hardened to a high degree, making them stronger and better-suited for mechanically straining applications, like vehicle suspension systems. Testing The aatm difference between 2H and 2HM nuts is in the testing. No products in the cart. Ruben- B7M y 2HM tienen menor resistencia y deben marcarse en consecuencia.

PM Metal provides guidelines with respect to fastener patterns and spacing to prevent this problem. Bolts with flattened Panhead with Allen. Protect legibility of markings Minimize exterior dimensional changes Maintain thread fit Chemical Composition Both 2H and 2HM nuts have the same chemical composition. Carbon steel fasteners is the most common type of steel used in fastener production.

ASTM A194 Grade 2H vs. 2HM

As for the torque, that is not an easy question since torque is notoriously unpredictable. These steels are typically medium carbon alloys, ggade as types and However, the minimum proofload for 2HM nuts is ksi, so it should have sufficient strength to work properly with B7 bolts.

This is the most common grade used in automotive applications.


Leave this field grase. These nuts are intended for high-pressure or high-temperature service, or both. Special department for odd size fasteners! Grade 5 steels are produced from unalloyed medium carbon groups, such as typeand are usually work-hardened to improve their strength.

The tests for 2HM nuts must also take into consideration 3 additional things during testing: If the bolts is B7 and the nuts installed is 2HM in term of quality and wstm of materials during bolt torquing have no effect or any significants regarding this matter?
