 Installing Expansion Anchors Expansion Anchor Installed Step 3. Anchor Installation Step 4. Securing the Anchor Boot Replace the anchor boot and align with holes in the concrete. Make sure the nut on the expan-sion anchor is threaded to the top of the threaded rod to prevent damage to the threads. Insert the expansion anchor through the base plate and into the hole in the concrete. Hit the expansion anchor with sharp blows until the washers are snug against the base plates. Tighten the nut to the recommended installation torque. Clean debris from holes using a wire brush, vacuum, or compressed air. Step 1. Prepping the Concrete Using anchor boot as a template, mark hole locations and move anchor boot out of the way. Drill a hole the same diameter as the expansion anchor to a minimum depth of ½’’ deeper than the anchor will penetrate to allow debris to fall during installation Step 2. Prepping the Hole Minimum thickness of fixture is a concern only when the anchor is installed at the minimum nominal embedment. When KWIK Bolt TZ anchors are installed at this embedment, the anchor threading ends near the surface of the concrete. If the fixture is sufficiently thin, it could be possible to run the nut to the bottom of the threading during application of the installation torque. If fixtures are thin, it is recommended that embedment be increased accordingly. (313) 393-0393 | www.brasco.com © 2017 Brasco International, Inc. All Rights Reserved.
