What type of screws have threads that taper to a point?

The correct choice is sheet metal screws, which are designed specifically for fastening thin materials. These screws feature threads that taper to a point, allowing them to penetrate metal sheets efficiently without the need for pre-drilling a hole. The pointed tip aids in the screw's ability to bite into the material quickly, reducing the risk of cracking or splitting the surrounding area.

Sheet metal screws are ideal for use in thin gauge applications, as their design provides a secure hold and excellent resistance to pull-out forces. The taper on the threads enhances their effectiveness in gripping the sheet material being fastened, making them a preferred choice for many applications in construction and manufacturing.

In contrast, metal screws may not have the same tapering design, as their primary function can vary. Self-tapping screws are designed to create their own threading in materials but may have a different tip design that is not exclusively tapered to a point. Wood screws, while they do have a pointed tip, are primarily designed for fastening wood and may not be suitable for metal sheets due to their thread design and material properties.
