For SI: 1 inch = 25.4 mm, 1 ft-lbf = 1.356 N-m. For pound-inch units: 1 mm = 0.03937 inch, 1 N-m = 0.7375 ft-lbf.
1. For use with the design provisions of ACI 318 Appendix D, ICC-ES AC308 Section 4.2 and ESR-2583
2. Torque may not be applied to the anchors until the full cure time of the adhesive has been achieved
3. These torque values apply to ASTM A36/F 1554 Grade 36 threaded rods
4. The maximum embedment is limited to 12 diameters for the horizontal and upwardly inclined installations and for installations in water-filled (flooded) holes with a carbide drill bit.
