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.

While not fasteners in the traditional sense, washers are often used in conjunction with bolts, nuts, and screws to improve their performance. Washers distribute the load of the fastener over a larger surface area, helping to prevent damage to the material being fastened and reducing the risk of loosening due to vibration. There are several types of washers, including flat washers, lock washers, and fender washers, each serving specific functions in various applications.

Wedge anchor bolts offer several advantages over other types of concrete anchors. Their wedge design allows for a high degree of load-bearing capacity, making them ideal for heavy-duty applications such as securing machinery, supporting steel beams, or fastening heavy signs to concrete walls. They also provide excellent resistance to shear and tensile forces, ensuring durability and resilience under various environmental conditions They also provide excellent resistance to shear and tensile forces, ensuring durability and resilience under various environmental conditions They also provide excellent resistance to shear and tensile forces, ensuring durability and resilience under various environmental conditions They also provide excellent resistance to shear and tensile forces, ensuring durability and resilience under various environmental conditionswedge anchor bolts for concrete.
