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 ).
