<DIV>I have been using 4/40 screws for years. I use aluminum rivets to fill the space between the screw and the engine holes. You just take out the nail from the new rivet and use the aluminum rivet. I don't remember the size of the rivet but there is one that fits perfect. You save a little weight and the aluminum bites the screw. I guarantee that will never come loose. When you tight the screw make sure that you squeeze the rivet a little so the head of the screw gets inside the rivet. </DIV>
