C Hook Wood Screws, also known as window hook screws, serve various purposes in carpentry and DIY projects. These screws feature a sharp, self-tapping point for easy installation into wood. The “C” shape of the hook provides a secure hold, making them ideal for hanging lightweight items like curtains, blinds, or decorative ornaments. To use, partially drive the screw into the wood using a hammer, then turn it clockwise until the hook is flush with the surface.
