What is the safety factor for HDI-TZ anchor ratings as published in Hilti HDI-P TZ and HDI-TZ Technical Supplement 2024?
Hello, I would like to know the safety factor of the ratings for HDI-TZ anchors as published in Hilti HDI-P TZ and HDI-TZ Technical Supplement 2024. As a comparison the catalog for HDI+ ratings indicates in the notes a safety factor of 4. If the HDI-TZ has something similar my design will work, so looking for confirmation. Thank you.

Hello,
The technical data for the HDI-TZ and HDI-P TZ is based on LRFD, so there will be no associated factor of safety. The technical data for the HDI+ is based on ASD, which is why a factor of safety is provided in Section 3.3.12 of the Anchor Fastening Technical Guide.
For additional assistance, please reach out to hnatechnicalservices@hilti.com or give us a call at 877-749-6337.
