I have one of these hasps and the Master round lock installed on a steel door at my remote hunting camp. it is the most secure lock and hasp that I could find. Someone tried to gain entry to my camp and beat on the lock and hasp with a hammer or some other steel tool. They put a few dings on the lock and hasp but never got in. I didn't even have to replace either the hasp or lock. A few tips, use 3/8" carriage bolts of the appropriate length ( allow for the thickness of the material being bolted to and the washer and nuts), carriage bolts are the ones with round heads that can not be removed from the outside. You may need a backer plate on the inside depending on the material that you have drilled through. A very secure heap and lock system.
