Bremick Wafer Head Screws are for many types of work, like those using roofing, sheet metal and wood materials. These screws feature a flat top surface and countersunk head, as well as a conical-shaped bearing surface providing an appropriate flush fit and bearing surface for wood and other softer materials which is why they’re often used to fasten materials together to aluminium or sheet metal. These also feature a drill point tip, meaning it can drill a starting hole so the threads of the screw can cut into the material, securing it into place. Zinc plating means it has ample rust protection that you can install anywhere even near moisture prone areas indoors. - Drill tip - Zinc plated for long lasting rust protection - For fastening materials to aluminium or sheet metal - Great for wood and other softer materials
