The 3/4 inch one is still a keel bolt, and a ground point. The keel is thinner there and probably has a sloping leading edge so that bolt is smaller as there is less keel for it to be buried in.
You really do need to know the diameter of your keel bolts to answer the question about torque value. My boat has a total of 8 keel bolts, but in 4 different diameters, the diameter depending on their location in the keel. The largest are even larger that those on the torque chart, the smallest is 3/4".
