1-1/4 Inch Black Phosphate Phillips Bugle Head Coarse Thread Drywall Screws are carbon steel screw fasteners designed for fixing gypsum board, drywall panels, and plasterboard to wood studs or wooden framing.
These screws feature a bugle head, Phillips cross recessed drive, sharp point, and coarse thread. The bugle head allows the screw to sit neatly into the drywall surface without tearing the paper face, while the coarse thread provides strong holding power in wood materials.
With a black phosphate coating, these drywall screws offer a clean black appearance and smooth installation performance for interior drywall construction and wood framing applications.

The bugle head is designed for drywall fastening. It helps the screw head sink smoothly into the gypsum board surface and reduces damage to the paper layer.
The coarse thread provides stronger grip in wood studs and wooden framing compared with fine thread screws. It is suitable for drywall-to-wood applications.
The Phillips cross recessed drive is compatible with common screwdrivers and electric screw guns, making it suitable for fast installation on construction sites.
The sharp point helps the screw start quickly and penetrate drywall and wood more easily, improving installation efficiency.
The black phosphate coating gives the screw a black appearance and smoother surface, suitable for standard interior drywall fastening applications.
