Malco No 7 Sizes X 1/2 in. L Slotted Hex Washer Head Sheet Metal Screws 100 pk

Malco Products, SBC got its start in 1950 when a young steel supply salesman, Mark W. Keymer, decided to manufacture and market a pipe crimper he had invented for use in installing the “new” sheet metal ductwork used with forced air heating systems. More tools soon followed, including the first hand seamer to employ compound leverage, a time saving hand notcher that made a V-shaped cut in one motion and a hand operated, snap lock punch to complete the basic sheet metal tool set.
