For drywall application, what is the recommended spacing for screws on the edges?

8 inches apart
12 inches apart
16 inches apart
24 inches apart

The correct answer is: 12 inches apart

For drywall installation, the recommended spacing for screws on the edges is typically 12 inches apart. This spacing is important because it ensures that the drywall is securely fastened to the underlying structure, providing adequate support and minimizing the risk of sagging or movement over time. Proper screw spacing helps to create a solid surface for finishing and reduces the chances of cracks appearing in the drywall due to shifting or settling. When screws are spaced correctly at 12 inches along the edges, it allows for even load distribution and better resistance to impacts or stress. This is particularly vital in high-traffic areas or places where the walls may experience significant wear and tear. The other spacing options do not meet the recommended guidelines. Wider spacings like 16 inches or 24 inches could lead to insufficient support, increasing the likelihood of failure in drywall integrity, while 8 inches may be unnecessarily close and can create more work without providing additional benefits in most applications.
