Good question - I think the spinners with my Vintage knock offs are some sort of aluminum. Knowing how easy it is to gall and strip regular fastners in aluminum heads and intakes I've wondered about their durability and beating on them. My Corvette knock offs have chome plated steel knockoffs and as long as there is a little anti-sieze on them I can beat on them all I want.
