Chemical timber fastening epoxy???
(OP)
I am an Australian forum user and I was after some info on the existence of a timber epoxy used to fasten threaded rods into timber beams. Does it exist? Are there technical resources available with design pullout values etc? I know tasbeam used to publish design data years ago using a hilti and ramset product. They don't do that anymore. I haven't seen anything used since. Maybe there is a reason for that?????

I have not investigated where they are getting the values from but the fine print says "testing divided by a reduction factor of 4." Probably worth it to look up the Code Evaluation report. Essentially they are assigning a withdrawal value of 4490 lbs for a 10" embedment with epoxy.

The AITC has long recommended against the use of any tension values for nails in end grain, which, in effect, the rod becomes. Just feels funny to me and I would never use it without further justification beyond any report from Simpson and the State of Florida...

I guess I will have to check my old tables the pullout for the same diameter and depth lag screw in side grain when I get back into the office. I have to prove this to myself, one way or the other.
