Materials and Surface Treatment: Typically made from carbon steel with a galvanized finish, presenting a silver luster.

Primary Uses: Commonly employed in woodworking and furniture manufacturing to connect wooden components (such as table legs or armrests) to metal brackets or other parts secured with nuts.

Installation Method: Requires pre-drilling a pilot hole in the wood, followed by screwing the wood-threaded end into the wood using a nut or specialized tool.
