While most wood screws are made out of steel, it's better to use copper, brass, bronze or nickel screws for jobs where there's a risk of corrosion. These are extremely high quality solid brass material to be used in wood working conditions. Whether you are looking for corrosion resistance or the 'beautiful brass look" these screws could be your ideal choice. The flat-head screw is the woodworker's friend, for he will use this type of screw almost exclusively to hold together all sorts of cabinets, bookcases, stair threads, tables, benches and a host of other items. Usually a cone-shaped depression is made with a countersink tool to hold the head of the screw; and once put in place and tightened the head of the screw is covered with wood putty, sanded down and coated with a wood finish just like the rest of the woodworking project. Flat-head screws also get used in such general construction tasks as hanging drywall, mounting door hinges, mounting cabinets and installing tabletops.
