Black collated drywall screws are specialized screws that have been engineered for the efficient installation of drywall. They are often coated with a black phosphate finish, which not only enhances their rust resistance but also contributes to their aesthetic appeal. The term collated refers to the method in which these screws are packaged and organized, typically in strips or coils. This collating allows for quick and easy installation, particularly when using a screw gun or drywall screw gun, significantly speeding up the process of hanging drywall.

Once the bolt is pushed through and the nut is tightened from the front side, the wings expand against the inner surface of the drywall, creating a secure anchor point. This design ensures that the bolt not only holds the weight of the mounted object but also withstands any pull-out forces.
