White hex head self-drilling screws are specialized fasteners designed for various construction and DIY projects. These screws feature a hexagonal head that provides a robust grip for tools, allowing for easy installation and removal. The “self-drilling” aspect refers to their ability to drill their own hole as they are driven into the material, eliminating the need for a pre-drilled pilot hole. This quality saves time and reduces labor intensity, making them particularly appealing for large-scale projects.
