Not at all. When you look at the physics of it the tendons & muscles that control your hand are far far smaller than those of your back and traps etc. Although they are very powerful they just cannot keep up with other muscles in terms of weight. For example when doing shrugs at your heaviest your grip will not be able to sustain the weight that your traps can move.

I think straps should only be used for shrugs and deadlifts BTW. and then not for warm up sets etc, just for when your at the limit and actually need them.
