Installation Guide
Proper installation is critical to maximizing the performance of Keyed Expansion Mechanical Anchors. Follow these steps for optimal results:
- Drilling: Use a standard rotary hammer to drill a hole to the specified diameter and depth. Ensure the hole is thoroughly cleaned of debris using a vacuum.
- Undercutting: Expand the base cavity with an undercutting drill bit. This step is mandatory for mechanical interlock, ensuring a secure connection.
- Insertion: Insert the anchor assembly until it is flush with the substrate surface.
- Tightening: Tighten the nut to 35 Nm torque to activate the cone expansion, creating a robust bond.
