Description
These stainless steel Phillips pan head self-tapping screws are the industry standard fasteners for light steel keel and drywall construction projects. Specially engineered for fastening gypsum board, metal profiles, and light steel frames, they deliver reliable performance in both interior and exterior building applications.
Made of high-quality stainless steel, these screws offer excellent corrosion resistance, preventing rust even in high-humidity environments such as bathrooms, kitchens, or commercial buildings. The pan head design provides a large bearing surface, ensuring a secure grip on thin metal keels without pulling through or damaging the material. The sharp, self-tapping tip easily penetrates light steel profiles and gypsum board without pre-drilling, significantly speeding up installation on large construction sites.
The full thread design ensures strong holding power, keeping drywall panels firmly attached to light steel frames over time. These screws are widely used in partition walls, suspended ceilings, and other drywall construction projects, offering consistent quality and durability that contractors trust.
