Featuring a recessed double countersunk head, these screws offer increased strength beneath the head, reducing the risk of shearing. Sharp milling ribs assist with effective countersinking, eliminating the need for pre-drilling and ensuring a flush finish. The innovative ‘Saw Fix’ serrated thread technology, combined with a sharp, wide, and deep thread, allows for fast and efficient insertion into a variety of materials, including hardwood, softwood, plywood, chipboard, MDF, uPVC, and thin sheet metal. Many sizes also feature an oblique-angle sharp gash point, enabling a quicker start, self-drilling capability, and reducing the risk of wood splitting. Designed for versatility, Vortex screws are compatible with both impact and non-impact drivers, with a free impact driver bit included. The high-quality zinc and yellow plating provides excellent corrosion resistance, while the Gleitmo dry lubrication ensures smooth and effortless driving.
