I just look at a regular hex bolt and the head has so little surface area, but I guess you are saying that is all that is needed and the head of the bolt is stiff and therefore won`t bend?

Ok so I gave the L bolt some more thought, is the issue the following: when it is loaded in tension, it will naturally want to torque and in doing so it could break the concrete. So what you guys are recommending is a simple anchor bolt, and if I can get a 1/4 inch plate sandwhiched between...
