Flat-head stove bolts 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. #6-32 coarse thread x 1/2 in. length.
