Corrugated Fasteners are a common alternative to traditional nails, screws and dowels when it comes to joining woods. They can be used at many different types of wood joints, and are one of the most common fasteners for joining mitered joints. Corrugated fasteners are used for both finish carpentry, like tables and furnishings, and rough carpentry, including components that are hidden from view. A corrugated fastener may also be used to join small or delicate pieces of timber, which may be damaged by nails or screws.
