Overview
Expansion anchors hold by friction and expansion when the nut is tightened; undercut anchors form a mechanical key at the bottom of the hole. They carry load immediately after installation, with no curing time.
Minimum edge distance, spacing and concrete thickness must be respected. In cracked concrete or seismic applications, choose anchors assessed for cracked concrete.
