Yep, you need some serious reinforcement if your deck is only 1/2" think - even if you through-bolted (which you should always do- never use any kind of self tapping screws for anything with any loading on it), you would likely rip those bolts out too. A plywood square on BOTH sides of the deck would be even better.
