Description
Sleeve Anchors, sometimes called Dyn-A-Bolt Fasteners are designed to be used in solid concrete, brick or block base material.
They work by inserting them into a hole drilled into concrete. Turning the nut pulls the working end of the Sleeve Anchor up through the sleeve, expanding and anchoring itself securely in concrete, brick or block.
Drop In Anchors are female concrete anchors designed for anchoring into concrete. Drop anchor into pre-drilled hole, use setting tool to expand the anchor into concrete.
They are lipped to ensure that Anchor avoids going into drilled hole and are internally threaded and for use with Bolts or Threaded Rod.
