Some Cinelli stems came with aluminum bolts, and they work just fine. The long bolt's function is to draw up the wedge, which is what actually holds the stem. If it is going to break, it'll break when you tighten it. After installation, the bolt isn't subject to torque or shear, and isn't really holding anything together, which is why you generally have to whack the head to free the wedge to release the stem. Obviously you should inspect the bolt to see if there is any deep pitting or corrosion on it (usually white powder). Also, use some anti-seize compound on the threads & under the bolt head.
