5 Abandon the hole if you should hit a reinforcing bar or the hole breaks

through. A minimum of two diagonally opposite anchors are required for

this application.

6 Remove any debris from the hole with a blowout bulb or compressed air.

Use a vacuum cleaner to dispose of the debris.

7 Insert the anchors into the holes. Use the manufacturer’s setting tool to

install each anchor flush with the surface of the concrete. Use the Hilti

HST 12.7 mm (1/2 in.) setting tool, manufacturer part # 000329805 or

equivalent.

8 Position each column over the anchors.

9 Insert bolt, metal washer, and shoulder washer into the pedestal hole, as

shown in the Figure 124 on page 361. On the far side of the pedestal

flange, thread a plastic washer, a metal washer, and the nut onto the bolt.

Insert the bolt into the concrete anchor.

10 Tighten the nut to the pedestal flange and torque it to 34 J (25 ft-lb) using

a 20 mm (3/4 in.) socket wrench. Do not overtighten.

11 Repeat steps 8 to 11 for remaining bolts.
