able, If the fit is snug there is nothing wrong with just driving the screws in. If you can drive the screws in without stripping the heads out you don't have to tap them. As brad pointed out if everything is not pulled up tight if you thread it it's not going to pull up snugly. It just makes the job a little easier to get the washers and nuts on if you don't have to worry about shoving the bolt back through. If you use a self locking nut it's going to turn into a two man job anyway. If the the old screws aren't bent or it doesn't look like the joints been working I don't think you need to worry about adding more fasteners unless you're going to the flemish cap in october.
