The CHENGFIX Concrete Screws Kit is a comprehensive fastening solution designed for tackling tough masonry and concrete applications. This 49-piece assortment includes five size variations — #1/4x1-1/4" (15 pcs), #1/4x1-3/4" (10 pcs), #1/4x2-1/4" (8 pcs), #1/4x3" (8 pcs), and #1/4x4" (8 pcs) — giving you the right screw for virtually any job. Each screw features a flat Torx (TORX) drive head for a secure, slip-resistant fit, a conical diamond point for faster drilling into hard surfaces, and a high-low thread design that cuts quickly and stably into concrete and masonry. The blue coating adds an extra layer of durability and corrosion resistance. A drill bit is included in the kit, so you have everything you need to get started right away. All screws are neatly organized in a reusable plastic storage case, making it easy to find the right size and keep your workspace tidy. Ideal for contractors, DIY enthusiasts, and homeowners alike.
