Do you have a bench grinder? I've made several custom tapered hex wrenches by taking whatever SAE size allen/hex key is larger than 5mm and tapering it down to pound into a stripped dust cap to screw it out. To my knowledge, this is the only possible use for SAE sized hex keys. Lord knows they don't fit anything else :shrug:
