Sheet Metal Screws

Industrial sheet metal is made of heavy-duty material that cannot typically be fastened with traditional or wooden screws. Primarily used in construction and manufacturing, sheet metal screws are industrial fasteners specifically designed to secure strong sheet metal to other metal objects and other surface materials. Sheet metal screws are recognizable from standard screws by the external threading that covers the entire shank.

Sheet Metal Screw Head Styles

Sheet metal screws are available in several head styles to fit different installation needs. Pan head screws are a common general-purpose option with a slightly rounded top and wide bearing surface. Hex washer head screws provide strong torque and are often used in metal roofing, HVAC, and other heavy-duty applications. Flat head screws are countersunk to sit flush with the surface for a clean finish. Oval head screws offer a slightly raised, finished appearance while still seating into a countersunk hole. Truss head screws have an extra-wide, low-profile head that helps distribute pressure on thin sheet metal and other lightweight materials.

Point types should be considered for application, as well. Type A points have coarse threads with gimlet points to fasten wood and thin metals. Type AB points have fine threads with gimlet points, best used for more fragile materials. Type B points utilize blunt tips and spaced threads for various materials, including plastics, plywood, and thin metals.
