The data presented in this table is to be used in conjunction with the design criteria of ACI 318-19 Chapter 17, ACI 318-14 Chapter 17 or ACI 318-11 Appendix
D, as applicable.

Linear interpolation permitted for minimum spacing and edge distance.

Because of variability in measurement procedures, the published torque of an impact tool may not correlate properly with the above setting torques. Over-
torqueing can damage the anchor and/or reduce its holding capacity.

Additional combinations for minimum edge distance, c
