These #8-32 x 1/2 in. phillips flat head zinc-plated machine screws are supplied as a box of 100. Stove bolts like these are used to fasten metal parts together that go into a tapped hole, or through a hole and are 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 the fastened material.
