Hilti Kwik-Bolts is the brand name for the Hilti Corporation wedge anchor. The Kwik-bolt has been in existence for many years and has gone through a number of changes. The Kwik-bolt that Hilti currently sells is called the Kwik-bolt 3. The Kwik-bolt 2 comes before it and the original wedge anchor being called the Kwik-bolt. They are all essentially the same product with the changes being made to the clip, thread length and the process in which they are manufactured. The original Kwik-bolt's clip was a two-piece design with the two pieces being taped together allowing for the clips to move independently. The clips on the Kwik-bolt 2 and 3 are now a one-piece design with other new features as well. The anchor itself has changed from a full body design (outside diameter of the threads are the same diameter as the anchor body) to a design in which the outside diameter of the threads are larger than the anchor body. The Hilti Kwik-bolt was made in America for many years. But the product is now sent overseas to China to be manufactured.

It is important to understand how to properly and safely install a Hilti Kwik-bolt. Below are step by step instructions:

1. Using a hammer drill, drill a hole in the base material the same diameter as the Kwik-bolt being used. The depth of the hole must be a minimum of one anchor diameter deeper than the embedment of the anchor.

2. Clean the hole of any debris from the drilling process.

3. Using a hammer, drive the bolt into the concrete. The anchor must be driven into the concrete at least 6 threads below the surface of the fixture being attached to the base material.

4. Using a wrench, tighten the nut to the recommended torque.

Hilti® Kwik-Bolts are excellent anchors that deliver strong holding values and can be used in many different applications. It is important to use these anchors properly to ensure the best results.
