Drill size for 200 anchoring in concrete

I used 3/4" KB-TZ2 Concrete Wedge Anchors to install an automotive 2-Post Lift. Both the ALI (Automotive Lift Institute) and the lift manufacturer recommend checking torque on the anchors periodically. I have read on this forum (Re-Torqueing of Mechanical Expansion Anchors) the recommendation to re-torque wedge anchors no mo...

Hi, In case of damaging on applied firestop sealant/mortar, should we remove all sealant/mortar from opening and reapply again or just to apply some sealant for damaged area. for example: Cable Tray opening sealed by FS-one MAX then some drilling done as size of cable in sealant to laying new cable, shall we remove and reappl...

Do not see HIT HY-200 adhesive anchor option on Profis drop down list. Only HIT-HY-200 V3 option (ESR-4868) is on the drop down on Profis

Does Hilti recommend the use of split lock washers with HY200 epoxy holding 6 1/2” HASV36 HDG anchors in solid concrete?

When I toggle my load input from static to seismic in Profis, the Hilti Kwikbolt TZ2 selection disappears as an option. The ESR 4266 states the Kwikbolt TZ2 is applicable for use in all seismic Design Categories, A-F, for seismic loads. Why is this anchor unavailable for a selection in seismic loads using Profis?

In ACI318-14 section 17.3.2.2 you are allowed to use anchor rods up to 4" diameter and embedment deeper than 24". Profis does not allow to go larger than 2" and 24". Is there a way to use larger & deeper anchor rods in Profis?

I need a UL number for 2-hour protection of a bolt head in glulam beams and columns.

Using CIP anchors, I specified a plate or washer but understand that this doesn't affect the bearing area used for the pullout calculation. Can you please send an example of how the bearing area is calculated? Assuming a 3/4"diam anchor with only a hex head embedded, I would expect a bearing area of 0.82in^2, however the rep...

EOR wants epoxy on a horizontal thru bolt application. I don't understand how epoxy is supposed to stay in the hole when the bolt is pushed through the hole or how to get epoxy in the hole after the bolt is inserted. Any help with this would be greatly appreciated
