I used those big ass "12 nails with plastic washers from my Figjam Bucket Cooler for my tent, and while we didn't get any high winds last year, I'm pretty confident they would have held my tent down. The metal tent poles would have collapsed long before the nails pulled out. (By the way, I had a backup tent in case my main tent got shredded. Radical Self Reliance.) It was also inside a Monkey hut which helped shield the wind. Drive them in at a 90 degree angle to the load and they're pretty solid. Lag bolts would be even better.
