Does Hilti make a power-actuated fastener recommended for plywood direct to steal beam connection? I have a project with tight clearances and I'd like to attach the plywood diaphragm directly to the steel beams, instead of to a nailer.

Does the lightweight reduction apply to the install stall torque requirements of KB-TZ2 anchors?

I have a W10x49 steel column that we would like to wrap with a steel plate. What is the minimum plate thickness required, when coated with CFP-SP WB 120+, to achieve a 2-hour fire rating for the plate?

We are in a hospital renovation, and we are looking to create / maintain the fire rating of the floor where a few large pipes penetrate into our renovation space. This was previously an open hole and was concealed behind drywall. We must now meet fire code requirements and close the hole. We are hoping to use the composite she...

My questions were not responded 1 What values can be obtained for PAF in brick masonry ? 2 What is minimum thickness of concrete required at the end of PAF 3. What is minimum spacing between PAF for full capacity 4. PAF in the shell of concrete block. Is there any reduction if PAF doesn’t get full length embedment. Assume the ...

In hilti profis designing for yield using Hilti HIT HY 200 V3 Rebar, the result shows the development length ld. Does it mean that the post-installed rebar is already adequate for concrete breakout and bond strength(design for yield)? Because there is no design output for breakout and bond strength, only the ld?

Does the adhesive on the bottom portion of the HIT-Z rod break away when you torque the anchor? Do you have any video that shows how it behaves after applying torque? Thanks for your help!

I would like to know what Hilti thinks of this installation of its products and whether Hilti would think that these penetrations are actually going to stop the spread of smoke and fire. There is no annular space no rigid support on both sides and I think they just stuffed red sealant in there. I have lots more photos. Hilt...

I have a steel conduit penetrating a 2hr fire rated shaft wall, I have access to caulk only one side of the wall and the steel conduit doesn't have a sleeve. Is there any UL detail or can an engineering judgement be provided for this condition where only one side caulking will suffice?

Hi, According to ACI 318-19 Section 17.9.3, anchors can be installed at a spacing less than 5 × da, provided they are not torqued. However, for design calculations, a reduced effective diameter must be used to comply with the standard edge distance requirements. For example, if I install a 1 diameter anchor with a 20 embedment...
