Phosphated Self-Tapping Screw

Phosphated self-tapping screws are black-colored fasteners. The tint comes from a layer of phosphates on the surface.

This coating has low corrosion resistance, so the screws are mainly used for indoor work.

Phosphated self-tapping screws are most often used for joining wood structures, for example when assembling furniture. They are also used for finishing rooms with plasterboard sheets or sandwich panels.

The appearance of the fasteners may vary. The standard design is a sharp threaded shank with a small round head.

How to use

When driving into plasterboard, no pilot hole is needed — the material is soft and yields easily to the fastener. In wood, a hole must be made in advance, with a diameter smaller than the screw diameter.
