Answer :

In drywall application, the type of nail heads used are typically:

1. Domed: Domed nail heads are commonly used for drywall installation. The domed shape helps to prevent the paper of the drywall from tearing or being damaged during installation.

2. Flat or Concave: Flat or concave nail heads are also suitable for drywall application. These types of nail heads can be used effectively to secure the drywall in place without causing damage to the surface.

So, when working with drywall, it is common to use nails with domed or flat/concave heads to ensure a secure and damage-free installation process.
