Self-tapping screw 3.5x16mm for sheet metal LN KNAUF

The self-tapping screw from the LN series of the world leader KNAUF is a high-class fastener designed for connecting metal profiles and sheet metal parts in the construction of drywall substructures. Made of high-quality non-alloy steel, this model is distinguished by exceptional strength and precision. The product is equipped with a self-tapping fine thread and a sharp needle-shaped tip, which allows for quick centering and immediate fixation of metal elements to each other, without the risk of tool slippage and without the need for pre-drilling.

The surface of the screw is protected from corrosion by a professional phosphate coating, which guarantees long-term resistance against the influence of moisture and aggressive building mortars on the site. Its compact dimensions of 3.5 x 16 mm and the specific geometry of the head ensure tight and strong mechanical clamping of the details, while maintaining a low profile of the assembly. Manufactured according to strict German KNAUF standards, it guarantees consistent quality and high speed of work on the site, making this screw the preferred choice for the construction of stable and fire-resistant metal frames.

Purpose:

• Connecting and fixing thin metal profiles such as CD, UD, CW and UW to each other
