ESR 3027 table 1 jumps from 1 5/8" to 2 1/8" nominal embedment and the max torque goes from 19 to 40 respectfully, what would be the max torque for 1 3/4" embedment, thanks
Hi Kirk,
Thank you for reaching out. ICC ESR-3027 for the KH-EZ Screw anchor outlines the installation information for specific tested embedments and lists them as minimums until the next tested embedment is achieved. For example, the 1-5/8“ nominal embedment is listed as a minimum to follow until 2-1/8“ nominal embedment is reached. As such, the maximum installation torque listed for the 1-5/8“ minimum nominal embedment would be applicable for nominal embedments up to 2-1/8“. This is also reflected in Table 2.2 of the Instructions for Use.
For additional questions, please reach out to hnatechnicalservices@hilti.com.
Kind regards,
Sinan
