Prime Source 1-3/8" phosphate coated drywall nails are designed for attaching gypsum board to wood studs. The phosphate coating improves holding power and helps joint compound adhere to the nail head. The cupped head sits flush with the drywall surface for easy concealment, and the long diamond point reduces cracking during installation.
