That's a good idea too... could even JB weld a nyloc nut to the back of the t-nut... I have had very good results bonding metal to metal with JB weld... all you need is enough strength to resist the friction from the nyloc so it won't twist the nut off and JB weld has a very strong bond... but if its something that is repeatedly assembled / disassembled, loctite is the way to go; nyloc's have a limited number of cycles before they loose their grip.
