The Mini-Undercut+™ anchor is an internally threaded, self-undercutting anchor designed for performance in cracked and un-cracked concrete.  Suitable base materials include post-tension concrete (PT slabs), hallow-core precast concrete, normal-weight concrete, sand-light concrete and concrete over steel deck.  The Mini-Undercut+ anchor is installed into a pre-drilled hole with a power tool and a setting tool.  The result is an anchor which can provide consistent behavior at shallow embedments as low as ¾ of an inch.  After installation, a steel element is threaded into the anchor body.
