Bolt is an alloy of iron, carbon and other elements. But you can determine it yourself by getting yourself a blot; weigh it accurately in grams. In your kitchen, you should have a measuring cup graded in ml. Fill it with water to an accurate level, then immerse the bolt in it and see how much water it displaces. That would be the volume of your bolt. Then divide the weight by the volume, which will give you the density of your bolt. it should be somewhere between 7-8 g/ml(cubic cm).
