FAQ

What size drill bit for 3/8" drop in anchor?

To install a 3/8-inch drop-in anchor, you typically need to use a 1/2-inch drill bit. 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.
