Material properties for these grades include:. We export fasteners to: They are work-hardened a914 a high degree, making them stronger and better-suited for mechanically straining applications, like vehicle suspension systems. However, the minimum proofload for 2HM nuts is ksi, so it should have sufficient strength to work properly with B7 bolts.
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? These nuts are intended for high-pressure or high-temperature service, or both.
