Wood Screws vs Metal Screws: What’s the difference?
When preparing for a new project, it is important to make sure you have all of the right tools required for the build. When it comes to something as seemingly simple as choosing the right screws, going with a “one-size-fits-all” mentality doesn’t always cut it.
In terms of their similarities, metal and wood screws are both available in standard lengths ranging from ¼” to 3”, and both types can be drilled using the same tools. However, as their name suggests, wood screws are better suited for builds involving lumber, plywood and other materials made of wood. While it’s true that metal screws can be drilled into wood, their unique features make them better suited for working with softer materials.
Wood screws consist of four parts: the head, shank, threads, and tip. The tip’s sharp point will guide the screw precisely as it cuts into the material. The shank forms the screw’s core and the thread is wrapped around it. The thread cuts grooves which allows the screw to grip the material securely as the screw is driven deeper. This grip prevents the screw from being pulled out, securing the workpieces together.
Metal screws differ from wood screws in their design and function. Their design elements are specifically geared towards securing sheet metal to metal, plastic, fibreglass, wood, or other materials. They can also be used to attach hinges, hasps, brackets, and other types of hardware. In short, metal screws are designed to withstand the stress of holding together heavy metal pieces for an extended period of time.
