KB-TZ2 installation torque
It looks like the installation torque values for carbon KB-TZ2 1/2" and 5/8" anchors are not correct. The tech guide says 50 ft-lb for 1/2" dia. anchor, but it also shows 40 ft-lb for 5/8" dia. anchor. How does the larger dia. anchor require less installation torque?

Hi Yong-mook,
After further review, the installation torque values for the 1/2" and 5/8" carbon steel KB-TZ2 listed on page 299 of the Anchor Fastening Technical Guide are correct. These values were determined through Hilti's supportive testing process to achieve optimal pre-tensioning in each anchor.
