Does Hilti offer stp files that I can include in my solid model. I will also need recommended drill bits, epoxy grout and grout dispersing dev...

There is a direct substitution letter for HY270 to replace HY70 which indicates the values of anchors in the face of cmu are higher for HY270.

Hi HILTI I am designing post installed rebar anchor design for my pedestal. I have gone through the calculation report. Please go through the attached calculation report for my questions which needs clarification. Thank you.

I am comparing design output from Nucor's concrete filled diaphragm design to Hilti's published information from ESR-2197. Nucor shows the same Pnf Nominal Capacity for the X-ENP-19 (in my case 1603# for 22 ga). Table 2 of the ESR lists multiple values for Omega. My interpretation is that the ASD fastener capacity to the fr...

Afternoon, We installed firestop cast-in devices for metal decks (CFS-CID MD) sleeve in our building for new construction. The piping material for the system is mainly chem PVC. Is there something we could use in conjunction to this sleeve for us to obtain a 2hr. T-Rating? We are having some thigh clearances on the top side ...
