This 120-piece Flat Head Phillips Wood Screws are crafted from premium 304 stainless steel, ensuring exceptional durability, rust resistance, and corrosion protection. These screws are ideal for woodworking projects, providing long-lasting, reliable fastening. For harder woods, we recommend pre-drilling a pilot hole to achieve the best results (note: these screws are not suited for metal or wall installations and are best used at a low drill speed). Designed for aesthetics and functionality, the stainless steel screws have a silver finish that complements most hardware and furniture. The countersunk flat head allows them to sit flush with the surface, creating a clean, professional look while ensuring a tight, secure joint. As self-tapping screws, they are easy to install with a standard screwdriver, and for tougher woods, the included adjustable wood countersink kit helps ensure seamless installation. This kit is perfect for indoor and outdoor woodworking applications, such as furniture assembly and general hardware installation.
