through bolt in brick masonry
(OP)
I have a very basic question. When you bolt through masonry (through bolt), I know that you use a threaded rod with nuts and plate washers at each end of the bolt. Do you also need to specify some adhesive in the hole, like Hilti HIT HY 20? The through bolt detail in the tech note from the BIA doesn't show any. I guess that if you did try to put something in the hole like grout or adhesive, you would foul up the threads of the rod. I have never used a through bolt before, but I want to use one now. Any guidelines on properly detailing a bolt through multi-wythe brick masonry are greatly appreciated.

I'm sure others who have actually used this detail and know about its pro's and con's can be of better help.

If it is a repetitive loaded anchor, I would think more about using chemicals. I wouldn't think brick to be a very good repetitive load base anyway.
I don't think you need an adhesive with a through bolt with a plate washer and nut. If you have enough load to pull the plate washer and nut through the wall, that little bit of adhesive isn't going to mean squat.
If you have other questions, Hilti and Simpson have very good technical service departments. If you call them, they will most likely tell you the least cost and/or strongest connection for your wall even if it does not include one of their products. That is been my experience with them anyway.

I like the idea of putting adhesive in the hole to try to get a more even distribution of load. I think you could take a screen tube, cut one end off it, and put it through the hole. Then you could tape the cut end, and put your adhesive in. You could also tape the threaded rod so the threads don't get coated with adhesive as you insert it in the hole. You the then push the bolt through, puncturing the tape at the other end, and remove the tape from the bolt during the gel time of the adhesive. This is just my idea of a procedure, I am open to others suggestions or experience.
