Universal self-tapping screws are used for fastening materials to wood, chipboard, plastics, and thin metals, and can be used with plastic anchors for installation in concrete or brick. They feature a medium thread pitch, allowing them to work with both wood and metal sheets. The special shape of the tip and thread ensures fast, reliable, and easy driving. Types of universal screws depending on the material and coating type: galvanized – made of carbon steel with zinc coating; yellow screws – made of carbon steel with yellow zinc coating. Galvanized screws are protected against moisture, so they can be used for both interior and exterior finishing works. Screws easily penetrate metal up to 0.9 mm thick, plastics, wood boards, fiberboard, and other non-hard materials. Pre-drilling holes will be required for sheet metal thickness from 0.9 to 6 mm.
