GRK fasteners for camper jack bracket re-install

Thanks for the response, gentlemen. Most appreciated. While I can't change the framework (at least not without considerable work), I can upgrade the fasteners. These GRK exceed the specs of typical lag screws, have an aggressive thread (good bite), are very unlikely to rust AND they are torque head. These fasteners were an engineering requirement for certain parts of our house build due to superior shear strength. I just may go with these for the jack brackets. Thanks again.
