A 1/2" grade 2 bolt is capable of providing 8,000 lbs of tensile force. If you have a crash, what do you want to fail; the stud or your tee slot?
They don't use 12L14!!! I'll assure you of that.
The stud material cuts more like stressproof or 1144 material. It's tensile/yield strength is equivalent to a grade 5 to 8 bolt. Still way stronger than what is needed for the Hobby Machinists needs. It's machine-ability is that of 12L14, too.
For your needs, 12L14 is quite sufficient. In the industrial environment, I've seen people rip the entire tool post off of the compound on lathes before from not paying attention to what they are doing. It snapped off the stud at the tee nut and heavily damaged the tee slot on the compound, too. Pretty much destroyed the Aloris CA tool post and holder. And oh, knocked the headstock out of alignment, too! I'm guilty of ripping the adjusting screw off of a tool holder and destroying a threading tool I bought out of my own pocket one time many years ago. This was on a CA size tool post!
........While all these metal formulas are coming up ,is there a good site that explains them and there machining ability and uses also how to identify them ?.
Thanks
