Gypsum screws 1.5" are specialized fasteners designed for securing gypsum boards (drywall) to metal or wooden studs in wall and ceiling installations. Made of hardened steel with a sharp point and fine or coarse threading, they ensure strong holding power and quick penetration without damaging the board. Their phosphate-coated surface resists corrosion and provides excellent grip for joint compounds and finishes. Ideal for both residential and commercial drywall applications, these screws offer reliable, clean, and efficient installation.
