Hi. I just want to ask if you have a 3/8" dia wedge anchor that complies IBC for seismic design category D? If none, what alternative do you recommend that is 3/8" dia post-installed anchor?
Hi Sir Luowie. Thank you for reaching out. Yes, we have the HST4 wedge/expansion anchor which is not only approved for category D, but from A to F. Please see attached evaluation report for full details of the anchor including the excerpt of the section 3.0 where you will find the information on product use including seismic categories.
You may also utilize our PROFIS Engineering Software which allows you to design your anchoring-to-concrete connections using post installed and cast-in anchors. Link: https://profisengineering.hilti.com/ .

For Kwikbolt TZ2, base on the ESR there are 1/4in and 3/8in diameter? 
Yes. 1/4" and 3/8" diameter sizes of Kwikbolt TZ2 in other countries. I recommend coordinating with our dealer in Guam to check their actual stock availability and offering. Please let me know if you encounter any issues connecting with them. Thank you!
