I attended the webinar titled Roof Deck Connections & The Factors That Affect Performance (DCK101) I have not seen in my certificates list, the PDH certificate for this course. Can you provide that, please? This is the second means of contacting Hilti, i tried through the general contact means Best Regards, Todd Hawkinson th...

How much epoxy HIT-HY 200-R is required for a repair using: 1.25 dia. rod x 19 embedment in a 1.375 dia hole?

The bolts were installed in a hospital in the lower flute of 18 ga. W-type metal deck covered with 3.25 in. light weight concrete. The bolts have a minimum embedment of 3 1/2 inches and will have gravity and seismic loads applied to them. How can I determine the allowable shear, pull-out, and a combination of the two?

Is the Firestop system: HI/BP 120-03 (CEJ 421P) a tested-assembly by a certified laboratory such as UL or Intertek? Or is it an engineering judgment without testing? I've attached the document for reference in this submittal. If there is testing available, can you provide documentation?

I have dealt with a couple of projects involving Hilti's Kwik Bolt TZ and TZ2 expansion anchors. Once the anchors have been installed and torqued, it was requested that the anchor be completely loosened and the nut/washer removed so that the fixture could be modified in some way and then the anchor be re-torqued in the same ho...

Is there an anchor that is suitable for low strength concrete attachment? I am trying to attaching roofing membrane and insulation to an existing steel/conc roof deck and the concrete is not holding anchors well even with proper embedment. Glue also doesn't seem to work.

I watched the entire webinar of “The impacts of proper installation…” at 3pm EST today, but did not receive my certificate!

I need UL assembly details for sealant joints at top and bottom of 1 hr fire rated metal stud and gyp board fire barrier walls located between slab on grade and bottom of composite corrugated metal and concrete floor deck and from that elevated floor deck to underside of non-rated metal bar joist and 2x4 wood sub-purlin supp...

I attended the webinar for Joint Design for Fire and Sound Considerations (FS102), but have not seen a quiz link afterwards. Please advise.

Your detail WL2768 shows the membrane penetration as 3 or smaller. Is there a detail for a 4 clean-out penetration?
