Screws – Galvanized steel
Screws – Galvanized steel
Screws are probably the most commonly used fastener for woodworking. A screw is a metal pin with a head and tapered shafts that, because of it’s tapered shape, clamps two pieces of wood together. There are different types of screws available for different purposes.
Steel is an alloy of iron and carbon. Steel screws are a strong fastener, but they easily rust. This weakens the connection and stains the wood. That is why steel screws are often galvanized; ‘coated’ with a layer of zinc. They are commonly used for indoor wooden constructions.
