Which fastener is frequently used to attach drywall to wood framing?

1. Drywall screws

2. Wooden nails

3. Sheet metal screws

4. Concrete anchors

The correct answer is: Drywall screws

Drywall screws are specifically designed for attaching drywall to wood framing due to their unique thread design and head shape. They feature a sharp point that allows them to penetrate the drywall and the wood easily, creating a secure hold without splitting the wood. The fine threads are ideal for gripping the drywall material and ensuring it stays firmly in place. Additionally, drywall screws typically have a bugle head, which allows them to sink slightly below the surface of the drywall without tearing the paper, making them perfect for this application. This ensures that the finished surface is smooth and can be easily taped and mudded for a seamless appearance. While wooden nails could be a traditional option, they don't provide the same level of holding power and can be prone to splitting the wood. Sheet metal screws and concrete anchors are not suitable for this specific task, as they are designed for different materials and applications.
