I've got a low profile hydraulic torque wrench with a 1.5" hex. I want to make an insert that drops in to the hex to convert to male 3/4" square drive. I have a homebrew PID heat treat oven.

Max torque is 2000 lbs-ft, would 4140 do the trick?
What material would you suggest?
Thanks!

There are a lot of ifs with what you are making, but it will probably work. 4140 will through harden and it is very tough. I think S7 would be ideal. I'm guessing you want to end up with Rc45-50. Stabilize at 1500-1600 degrees F, quench in water. Move it around don't just drop it in a bucket.
