1 Maximum Installation Torque applies to installations using a calibrated torque wrench. 2 Because of the variability in measurement procedures, the published torque of an impact tool may not correlate properly with the above setting torques. Over-torquing can damage the base material, anchor and / or reduce
its holding capacity. 3 The minimum distance to hollow head joint is measured from the center of an anchor to the centerline of a hollow head joint( vertical mortar joint).
