Bonded fasteners consist of two main components the adhesive itself and a substrate or material that forms the bond. The adhesive is carefully engineered to provide a strong, durable connection while accommodating various materials, including metals, plastics, and composites. During the bonding process, the adhesive is applied to the surfaces of the parts to be joined, and then the parts are pressed together. The adhesive cures over time, forming a solid bond that can often surpass the strength of mechanical fasteners.

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.
