Self-drilling screw 4.2x13mm for sheet metal LB KNAUF

The self-drilling screw from the LB series of the world leader KNAUF is a high-class fastener, specially designed for fast and reliable connection of metal profiles and thick sheet metal parts in the construction of drywall substructures. Made of high-quality non-alloy steel, this model is distinguished by its exceptional strength and precision. Its key advantage is the self-drilling drill tip, which allows the screw to independently pass through the steel elements without the need for pre-drilling. This eliminates the risk of the tool slipping and significantly speeds up installation activities on the site.

The surface of the screw is protected from corrosion by a professional phosphate coating, which provides long-term resistance against the influence of moisture and chemically aggressive mortars. Its compact dimensions of 4.2 x 13 mm and the self-tapping fine thread guarantee a tight, secure and strong mechanical pressing of the sheet metal parts to each other. Manufactured according to the strict German standards of KNAUF guarantees consistent quality and extremely high speed of work, which makes this screw a preferred and secure solution for the construction of stable interior structures.
