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.

Structural bolts are made from high-strength materials such as grade 5 or grade 8 steel, making them resistant to corrosion and wear. They are heat-treated to achieve the necessary tensile strength, which can range from 120,000 to 180,000 pounds per square inch (psi). This high-strength capacity is crucial for withstanding the dynamic forces and stresses that structures face over time, including wind, seismic activity, and the weight of the structure itself.

The composition of 410 stainless steel is what sets it apart from other materials. It primarily consists of chromium, typically around 11-13%, which imparts its corrosion-resistant properties. This makes 410 stainless steel screws ideal for use in environments where exposure to moisture or chemicals is likely. However, it's important to note that while they offer moderate resistance to corrosion, they may require additional surface treatments like hardening and polishing to enhance their anti-corrosive capabilities.
