HIT RE500 V3 Adhesive Anchor - reduced edge distance with reduced installation torque

HIT RE500 V3 Adhesive Anchor - reduced edge distance with reduced installation torque

I am contacting you to inquire about the hilti product HY HIT500 adhesive anchor. I am working on a design project that involves attaching a bracket to the underside of a concrete slab using 3/4" diameter bolts. I have been using the hilti profis program to calculate the required embedment depth and spacing of the bolts. However, I noticed that the program has an option to allow for reduced installation torque for bolts that are close to the slab edge. I would like to know more about this option and how it affects the performance of the anchor. I'm trying to design 3/4" Hilti HAS bolt (HIT 500) at 2" away from the slab edge as shown in the attached diagram. My question is what is the minimum edge distance for 3/4" diameter HAS bolts (HIT 500) when using this option, and under what conditions is it applicable? Thank you for your time and assistance.

Hi James
This option in Profis Engineering refers to section 4.1.9 in the ICC-ES ESR 3814 that can be found under this link.
For edge distances cai and anchor spacing sai, the maximum installation torque shall comply with the requirements in the image attached. For any other questions, please feel free to contact us at ca.engineeringtechnicalservices@hilti.com.
