These came with a self tapping sheet metal screw that wouldn't keep them tight. I used machine screws and a little loctite on the threads to keep the nuts from backing off. They're very short as there isn't a lot of room for extra threads between the bottom of the shield and the manifold. I installed them on the engine before putting the manifolds on. Not the best way to do it since they needed a little adjusting to fit properly with the manifolds.
