| Diameter of Wedge Anchor | Minimum Embedment Depth |
|---|---|
| 3/8” | 1-1/2” |
| 1/2” | 2-1/4 |
| 5/8” | 2-3/4” |
| 3/4” | 3-1/4” |
How deep should wedge anchor bolts be in concrete?
2-1/2 inches

What is the Hilti bolt-TZ?
Over ten years ago, Hilti set unprecedented standards for designers and contractors alike with the Kwik Bolt-TZ — the first expansion anchor designed for structural seismic applications.
How do you install a Kwik bolt TZ?
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.
