Hilti Kwik Bolt TZ is the brand name used by Hilti, Inc. for its wedge anchors that are designed to resist static, wind and seismic shear as well as tension loading applications in uncracked and cracked normal weight concrete. The Hilti Kwik Bolt TZ or KB-TZ is a mechanical type expansion anchor that is torque-controlled and is made up of an anchor body, wedge clip, and a nut & washer. The Kwik Bolt TZ is manufactured in carbon steel that is zinc-plated as well as in type 304 and 316 stainless steel. The anchor body of the Kwik Bolt TZ is threaded at one end and tapered at the other. The wedge clip is fixed to the tapered part of the anchor body and moves freely around the tapered anchor body. The Kwik Bolt TZ is installed in a predrilled hole in concrete and is set by applying torque to the nut. When the nut is turned clockwise, the anchor is drawn up which moves the wedge clip down the tapered end of the body. This wedges it between the concrete and the anchor body.

Installation Instructions for the Hilti Kwik Bolt TZ

1. Drill a hole in the concrete using a hammer drill. The diameter of the hole is the same as the diameter of the anchor being used. The hole depth must be 1/4" deeper than the depth at which the KB-TZ will be embedded into the concrete. To ensure proper anchor location, use the fixture as a template.

2. Remove all dust and debris from the hole.

3. Using a hammer, drive the Kwik Bolt TZ into the hole. The anchor must be driven a minimum of 4 threads below the surface of the fixture.

4. Using a wrench, tighten the nut to the required installation torque for best results.

If the Hilti Kwik Bolt TZ is the correct anchor for your specific application, follow the installation steps above to help ensure that the bolt is installed properly and the job is a success.
