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.

The design of an M8 wedge anchor is simple yet effective. It consists of a threaded rod with a nut and washer, accompanied by a wedge-shaped expansion sleeve.

As the bolt is tightened, it pulls the wedge-shaped sleeve against the sides of the hole, creating friction and causing the sleeve to expand. This expansion locks the anchor securely in place, providing a strong hold that can withstand significant loads.
