DeWalt® Mini-Undercut+™ 3/8”-16 Internally Threaded Undercut Anchor

The Mini-Undercut+ anchor is an internally threaded, self-undercutting anchor designed for performance in cracked and uncracked concrete. Suitable base materials include post-tension concrete (PT slabs), hollow-core precast concrete, normal-weight concrete, sand-lightweight 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 3/4 of an inch. After installation a steel element is threaded into the anchor body.


  • Ideal for precast hollow-core plank and post-tensioned concrete slabs
  • Cracked concrete tested alternative to a mini dropin anchor
  • Redesigned ANSI carbide stop bit with enlarged shoulder for accurate depth
  • Anchor design allows for shallow embedment as low as 3/4 of an inch
  • Internally threaded anchor for easy adjustment and removability of threaded rod or bolt
  • Drill and drive the anchor with one tool for fast anchor installation


  • Tension zones, seismic and wind loading applications
  • Suspended Conduit
  • Fire Sprinkler & pipe supports
  • Cable Trays and Strut
  • Suspended Lighting
