Collated drywall screw special for steel plate max 2 mm

The drill tip and threads are designed for anchoring in steel up to 2 mm. The wings mill the hole in the chipboard. When the drill tip penetrates the steel, the wings break off, and the head sinks into the plasterboard without damaging the paper layer. Suitable for drywall installation where the innermost board is made of chipboard or plywood.
