Hilty is a misspelling of the name Hilti, Inc., which is a company that specializes in fasteners, tools, and accessories for construction trades.  Concrete Fasteners, Inc carries many of the same types of concrete anchors that are equivalent to the type of anchors  that Hilti, Inc. distributes.

Hilti has divided their steel mechanical fastener line into two categories:

Metal Anchors

  • HDA – undercut expansion anchors for heavy duty fastening, provide high holding values and closer to the unsupported edge distance than the standard expansion type anchor.   The HAD anchors are a very specialized concrete anchor, Concrete Fasteners does not carry this type of anchor.

  • Kwik-Bolt TZ – designed for use in seismic and cracked concrete applications in medium duty, and available in standard zinc plated carbon steel and stainless steel.  The TZ version of the Hilti Kwik-Bolt is comparable to the Power-Stud SD2@ that Concrete Fasteners carries.  The Power-Stud SD2 anchor is a fully threaded, expansion wedge anchor that is torque controlled and is designed for consistent holding values in uncracked or cracked concrete. It is available in the following sizes and can be ordered by calling 216-357-7433:

  • HCA Coil Anchor – utilizes coil threads for a stud anchor that is easily removed and is reusable.  Additional coils must be purchased to reuse the same anchor in a different hole.  This anchor is a specialized type of concrete fastener that Hilti, Inc. carries.
