The 40 MM Black Screw is a heavy-duty fastening solution designed for strong and secure fixing in drywall, wood, and light metal applications. Made from high-quality hardened steel, it offers excellent holding strength, durability, and resistance to bending. The black phosphate coating improves corrosion resistance and ensures smooth, easy driving.
Its sharp self-tapping point allows quick penetration, while the bugle head design ensures a flush finish without damaging the surface. Ideal for interior construction, false ceilings, partitions, and general fixing where longer screw length is required.
