Hanger bolts with metric thread and hex center, also known as dowel screws, are specialized fasteners designed for joining materials like wood and metal. They have a wood thread at one end and a machined metric thread at the other. The wood thread is designed to be driven into a pre-drilled hole in wood, while the metric thread is used to connect to a nut or a tapped hole in metal. The hex center provides a grip for tools like wrenches or hex keys, making it easier to tighten or loosen the bolt.
