Frequently Asked Questions - KB-TZ SS304 HILTI

What drill bit should I use for the Hilti KB-TZ SS304 anchor?

Use carbide-tipped masonry drill bits complying with ANSI B212.15.1994. The bit diameter must match the anchor diameter (e.g., 3/8 in. bit for 3/8 in. anchor).

Can I use the KB-TZ SS304 anchor in wood or grout-filled CMU?

No, the AT-System is not applicable for grout-filled CMU or wood fastening applications. This anchor is designed for concrete and solid masonry.

What is the minimum embedment depth for this anchor?

The minimum embedment depth (h_0) varies by diameter and application. Refer to the ICC-ES report or product labeling for exact values. Typically, it is between 1-1/2 in. and 3 in.

Do I need to clean the hole before installation?

For standard installations, clean the hole of dust and debris using compressed air or a vacuum. For non-hole cleaning installation, drill deeper to account for debris at the bottom (see instructions for step 1a or 1b).

What torque should I apply for installation?

Use a torque wrench set to the specified torque value for the anchor diameter. Typical values range from 20 ft-lb to 80 ft-lb (check product data sheet for exact values).

Is the KB-TZ SS304 suitable for outdoor or corrosive environments?

Yes, it is made of stainless steel 304 (A2), which provides good resistance to atmospheric corrosion. However, it is not recommended for highly acidic or chloride-rich environments.

Can I remove and reuse the anchor?

No, expansion anchors are designed for single use. Once installed and tensioned, they permanently embed in the concrete. Do not reuse.

What is the maximum concrete strength for this anchor?

The anchor is tested for concrete compressive strength from 2,500 psi to 8,000 psi. Check the ICC-ES report for specific capacity reductions outside this range.

How do I know if the anchor is installed correctly?

After torquing, the anchor should be tight with no rotation or pull-out. The clip or wedge should be fully expanded. Perform a visual inspection and ensure the marked depth is reached.

Where can I find the installation manual for KB-TZ SS304?

The user manual is available as a free PDF on notice-facile.com. You can also download it from the Hilti website or contact Hilti customer support.
