Stove bolts are also known as machine screws. These screws are used to fasten metal parts together that are going into a tapped hole or through a hole and being held by a nut. A nut of the same finish and threading for proper fit is included. Fasten with a screwdriver to reduce the risk of over-tightening and to protect the screw and fastened material. Made of steel, these screws are zinc-plated for moderate corrosion protection.
