Frequently Asked Questions - KB-TZ2 CS HILTI
What is a Hilti KB-TZ2 CS anchor?
The Hilti KB-TZ2 CS is a torque-controlled expansion anchor made of carbon steel with zinc plating. It is designed for high-load applications in cracked and uncracked concrete.
How do I install a KB-TZ2 CS anchor?
Drill a hole to the specified diameter and depth, clean the hole of dust and debris, insert the anchor, then tighten the nut to the manufacturer's recommended torque. The expansion sleeve will wedge against the concrete, creating a secure hold.
What drill bit size is required for KB-TZ2 CS?
The drill bit diameter matches the anchor diameter (e.g., M10 anchor requires a 10 mm drill bit). Always use a drill bit with a hardness suitable for concrete.
What torque setting should be used for installation?
Torque depends on the anchor size. For example, an M10 anchor typically requires 40-60 N·m. Refer to the technical data sheet for exact values to avoid over tightening, which can damage the concrete.
Can the KB-TZ2 CS be used in cracked concrete?
Yes, the KB-TZ2 CS is specifically evaluated for cracked concrete applications, making it suitable for seismic zones and structural connections where cracking is possible.
How can I remove a KB-TZ2 CS anchor if needed?
To remove, fully unscrew the nut and push the anchor into the hole, or use a extraction tool to pull the sleeve out. The remaining hole can be filled with epoxy mortar if no longer needed.
Is the KB-TZ2 CS corrosion resistant?
The anchor has a zinc plating that provides moderate corrosion resistance for dry indoor environments. For outdoor or humid conditions, choose a stainless steel version (e.g., KB-TZ2 SS).
What safety precautions should I take during installation?
Wear safety glasses, hearing protection, and gloves. Follow the drilling parameters and use sharp drill bits. Ensure the concrete is sound and free of hidden reinforcement.
Are setting tools available separately for this anchor?
Yes, Hilti offers setting tools that ensure proper installation depth and torque. These tools help achieve consistent results and are available from Hilti distributors.
What is the load capacity of the KB-TZ2 CS anchor?
Load capacity varies with anchor size and concrete strength. For example, an M10 anchor may hold approximately 6 kN in tension in C20/25 concrete. Always verify with the engineering data for your specific application.
