Drop in Anchor - Copper: This is a specialized fastening solution crafted from copper, designed for securing objects to concrete surfaces. High - purity copper provides excellent corrosion - resistance, making it suitable for environments where rust and corrosion could be a concern, such as in electrical installations or marine construction. The precision - machined surface, often with a textured pattern, enhances the grip within the concrete. When inserted into a pre - drilled hole in concrete and combined with a suitable bolt or screw, it expands to create a firm and stable connection. It is an ideal choice for construction projects, electrical equipment mounting, and marine structure fixing, ensuring long - lasting and reliable fastening.
Instructions for Use：
Determine the appropriate size of the Copper Drop in Anchor according to the weight and load of the object you want to fix, as well as the thickness and quality of the concrete. Select an anchor with a diameter and length that match the requirements.Hole Drilling: Use a drill bit suitable for concrete to create a hole in the concrete surface. The diameter of the hole should be slightly larger than the outer diameter of the anchor, and the depth should be sufficient to accommodate the entire length of the anchor, with a little extra space for expansion.After drilling, thoroughly clean the hole to remove any dust, debris, or concrete chips. This ensures that the anchor can be inserted smoothly and make full contact with the concrete.Gently insert the Copper Drop in Anchor into the cleaned hole, making sure it is vertical and sits flush with the concrete surface.Insert a compatible bolt or screw into the anchor. As you tighten the bolt or screw, the anchor will expand inside the concrete, creating a secure fastening. Regularly check the tightness of the connection, especially in applications with heavy loads or in environments subject to vibration
