Sheet metal screws, otherwise known as tapping or self-tapping screws are designed for connecting thinner metal objects to one another or connecting metal to wood, plastic, and other materials; sharp threads draw material together and ensure a secure hold. Sheet metal screws (or SMS's) are made from hardened steel so that the threads create their own mating thread in pre-drilled holes. Sheet metal screws can also be used in other materials, such as wood. Sheet metal screws come in different types. Type A has a coarse thread and sharp point. Type B has a fine thread and a blunt point. Type AB combines the two, with a fine thread and a sharp point.
