wall butterfly anchors

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.

One of the primary advantages of hex socket head wood screws is their durability. The materials used in their construction, typically hardened steel or stainless steel, provide excellent resistance to corrosion and wear. This makes them particularly suitable for outdoor projects or in environments exposed to moisture. Additionally, the hex drive reduces the risk of slipping, allowing for greater torque application and minimizing damage to the screw head, which is especially beneficial when working with tougher materials.
