Coarse-thread drywall screws, available collated or loose, are ideal for fixing plasterboard to timber structures. Their coarse thread ensures optimal grip in wood.

Fine-thread drywall screws, available collated or loose, are ideal for fixing plasterboard to metal studs (up to 0.9 mm thick).

Phosphate-coated

Drywall screws are phosphate-coated in anthracite. This chemical treatment alters the surface layer of the base material, so it no longer behaves like the original metal surface. This helps prevent the screws from rusting after plastering, avoiding brown stains in the plaster finish!
