I am trying to specify a load for Torque testing of KB-TZ2 expansion anchors. We need to specify the torque test for carbon steel, stainless and conditions into metal deck and any other possible condition on the project. In the ICC report for the KB-TZ2, values for installation torque are reported. Is the installation torque a...

What does the shear load, Q, in lb/ft that is input in the Diaphragm Design module represent? Is it the total shear load over multiple supports (whole roof or floor for that zone possibly), shear load between any two supports, shear load along one support, or something else? How does the defined shear load get distributed in t...

I am trying to determine how much mortal to dispense into a 2.25 diameter hole 30 deep for a 2 diameter fully threaded anchor bolt. I have drawn this anchorage in 3D in SolidWorks...because the Hilti app STOPS at 1.25 diameter, just like the Hilti charts do. When I check my 3D model against the app by changing it to a 1.25 dia...

Curious if there is a specific nailing pattern for installing 7/16 wall sheathing to steel studs and a pattern for installing 1/2 on a roof, I am quoting a job in Kalamazoo Michigan that is going to be a 2 story house, framed up completely out of metal studs and metal trusses. Not sure if it has to have some screws and nails o...

I need to attach a steel section to an unreinforced clay masonry wall to transfer loads from the existing joist to the wall . (the existing joists are embedded into the wall and are rotten). I need to attach an angle to the wall to capture the end of the joist that is not rotten. Building was built in 1917. see attached d...

Can we ignore concrete blackout check (aka, anchorage calculations) if we are to provide a full development length Ld for the post installed dowel rebar instead of the shallower embedment depth. Please let us know all the conditions to check to ignore anchorage design approach and use development length approach. Thank you.

Can we get a Hilti tech to come on site same day to recalibrate a pull test machine?

Will you please provide comments that directly address the client comments shown in the attached PDF? I am providing structural design consulting for a large industrial client. The improvements include platforms with steel checker plate. We specified Hilti products S-FCP and X-ST-GR for attaching the plate. The client posed...

Hi, I don't see HIT-Z rod on the RE 500 installation manual. Is HIT-Z not compatible with RE 500? Also, I understand that with the design of HIT-Z rod, the drilled hole does not to be cleaned. If we clean the hole before installing the HIT-Z rod, does it affect the strength of the anchoring?

customer has 258022 HIS-N 5/8X6-5/8 INSERT. what size hole should he drill to get the correct fit of his inserts?
