A wafer head screw, as the name suggests, has a flat, thin, and circular head, resembling a wafer. The head is usually larger than the screw's body, providing a broad bearing surface that distributes the load evenly and reduces the chances of damage to the material being fastened. The self-tapping attribute refers to the screw's ability to cut its way through the material it is inserted into, forming threads as it goes, hence the term self-tapping.

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.

The process of installing a bolt anchor with resin is meticulous. First, the anchor hole is drilled into the substrate to the correct depth and diameter. Then, the resin cartridge is placed in the hole, followed by the bolt. The resin is activated by inserting a setting tool or by applying pressure, causing it to expand and fill the hole The resin is activated by inserting a setting tool or by applying pressure, causing it to expand and fill the hole The resin is activated by inserting a setting tool or by applying pressure, causing it to expand and fill the hole The resin is activated by inserting a setting tool or by applying pressure, causing it to expand and fill the holebolt anchor resin. As the resin cures, it forms a strong bond with the bolt and the surrounding substrate, creating a steadfast anchor point.
