I don't believe that the bolts are buried or tapped into the keel, mitiempo, they are countersunk into a flange on the top of the keel. The shear strength of the bolt is still the same, and the amount of thread engagement necessary to obtain full tensile strength is only as large as the nut. It was surprising for me to learn how little thread engagement is necessary to obtain full strength in a bolt.
