T-nuts; heat treat or not?

I use an aluminum T-Nut to hold a indicator on the mill. I threaded one end of a 3/8 shaft to fit the T-Nut. The indicator bracket slides over it and locks at any height. 
If you make T-Nuts, make sure  you deform the thread at the bottom , prevents the studs from chewing up the mill slot. Store bought T-Nuts are made that way. I do this with a hammer and cape chisel.
