expanding metal hollow wall anchors

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. When installed, the anchor is drilled into a pre-drilled hole in the concrete, and then the bolt is inserted and tightened. 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.

One of the primary advantages of the 3/8 inch Tek screw is its strength. These screws are made from high-quality materials such as stainless steel or hardened carbon steel, which ensures durability and resistance to corrosion. This makes them ideal for both indoor and outdoor projects where exposure to the elements is a concern. Their strength also means they can bear significant weight, making them indispensable in load-bearing applications.
