We’ve expanded our portfolio size with even more cracked concrete, seismic approved expansion anchors, and we’ve increased standard length options giving you the ability to pick the perfect size anchor for the job. Hilti has also increased our approvals for embedment depths, providing the best performance in the thinnest of slabs and the KB-TZ2 is the only expansion anchor with diamond cored hole approvals. With new functional coatings and a unique wedge design, Hilti has created expansion anchors with 20% greater tension values compared to our previous KB-TZ, and the best edge and spacing in the industry. Offering increased performance, an expanded portfolio, and more approvals, the KB-TZ2 and KB1 can be used in more application and jobsite conditions than any other expansion anchor. Start making anchoring easier with the KB-TZ2 and KB1.
