How long of screws for ceiling drywall?

Ceiling drywall is cut to size and fastened to the framework using screws. Screw length for standard 1/2-inch drywall should be at least 1 1/4 inches to give you the penetration you need in the ceiling joists or framework. Usually for thicker, 5/8-inch drywall, you typically want to use a 1 5/8-inch screw. The choice of screws is determined by the specifications of a suspension framework or grid system in aluminum ceiling systems. Securing aluminum ceiling panels usually needs metal screws or fasteners, to install these panels solidly to ensure longevity and stability. The lengths of approved screws are necessary to attach the aluminum panels or drywall without damaging the material or reducing its structural strength. Take proper precautions, including following manufacturer instructions and consulting qualified professionals to ensure that the screws are suitable for your particular use case.
