This allows for a proper fit that ensures the anchor can be securely placed into the drilled hole. What is a drop in anchor? A drop-in anchor is a fastener used in concrete, brick, or stone materials to create a secure connection point for bolts or threaded rods. It consists of an internally threaded sleeve and a cone-shaped expander plug that, when installed correctly, provides a firm hold. How does a drop in anchor work? Drop-in anchors are installed by drilling a hole to the necessary depth in concrete/masonry. The anchor is inserted with its lip flush against the surface, and a setting tool drives the internal plug into the sleeve. This creates a dependable anchor point for attaching machinery, fixtures, etc.
