An anchor fastener, as the name suggests, is a device designed to securely fix an object or structure into a base material. It comes in various forms - from screws and bolts to adhesives and expansion anchors - each tailored for specific applications and substrates. They provide a robust connection, distributing loads evenly and preventing any potential slippage or detachment. For instance, in concrete structures, anchor bolts are used to anchor steel columns, while in woodworking, dowel pins serve as anchor fasteners for joining pieces of wood.
