Our zinc plated steel Sheet Metal Screws feature a sharp Type A or AB style point with a more closely spaced thread form that allows their use over a wide range of materials and material thicknesses. They are available in head styles such as Hex, Pan, Truss, Countersunk Flat or Oval Heads. They feature a clear zinc chromate plating to provide protection against normal atmospheric corrosion, but they will rust when exposed to the elements, moisture or chemicals.
