The Atomic+ Undercut anchor is a heavy duty undercut anchor which is
designed for consistent performance in cracked and uncracked concrete. Atomic+
Undercut anchors are available for standard installations and for through bolt
applications where the fixture is already in place.
The Atomic+ Undercut anchor is installed into a pre-drilled hole which has
been enlarged at the bottom in the shape of a reversed cone using the Powers
Undercut Drill Bit. The result is an anchor which transfers load mainly through
bearing, and unlike a typical expansion anchor is not dependent upon friction
between the expansion sleeve and the concrete.
