Hi Paul,
There is not a range of installation torque for the KH-EZ screw anchor as the installation torque value specified in ESR-3027 and the Instructions For Use in concrete is the value that should be applied. An important note, however, is that the KH-EZ screw anchor is not torque-controlled like expansions anchors. Screw anchors instead rely on keying to develop the capacity. The torque is to ensure the fastened material is properly clamped.
