They are mostly come with partially covered threads with sharp edges and narrow point.

3. Drywall Screws: ( Types of Screws )

4. Sheet Metal Screws: ( Types of Screws )

Sheet metal screws is used to fasten hard surfaces as they are able to dig easily into hard metal surfaces. They are mainly used to tighten metal pieces but usable also in plastic, rubber and wooden type of materials. They have various shapes and sized with different head styles like flat, truss, hex, oval, etc. depends upon the applications. They are fully covered with threads with sharp pointing edge.
