This section contains the <br /> Limit State Design tables with unfactored characteristic loads that are based on the published loads in ICC Evaluation Services <br /> ESR-3027.These tables are followed by factored resistance tables. The factored resistance tables have characteristic design <br /> loads that are prefactored by the applicable reduction factors for a single anchor with no anchor-to-anchor spacing or edge <br /> distance adjustments for the convenience of the user of this document.All the figures in the previous ACI 318-14 Chapter 17 <br /> design section are applicable to Limit State Design and the tables will reference these figures. <br /> For a detailed explanation of the tables developed in accordance with CSA A23.3-14 Annex D, refer to Section 3.1.8.Technical <br /> assistance is available by contacting Hilti Canada at(800)363-4458 or at www.hilti.com. <br /> Table 9-Steel resistance for Hilti KWIK HUS-EZ I and KWIK HUS-EZ E 1411 <br /> carbon steel screw anchor',' <br /> Nominal Internal Seismic <br /> anchor thread Tensile' Shear° shear' <br /> diameter diameter N V V <br /> sar sar sar,eq <br /> in.
