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.

Resin, on the other hand, plays a pivotal role in enhancing the stability of the bolt anchor. It is a two-part epoxy system consisting of a resin and a hardener. When mixed, they chemically react, forming a solid that can fill voids, bond surfaces, and strengthen the anchor's hold. Resin anchors offer advantages over mechanical anchors, particularly in situations where the substrate is weak or porous, or where vibration resistance is essential.
