I've run into the same problem. I was attaching brackets to treated yellow pine with 1/4 inch lags. They would go in OK with a pilot hole, but if you had to loosen them up they would twist off. I suppose the pitch in the pine was acting as glue. These imported fasteners are by and large garbage.
What I have started using are called "construction screws". Sorry, I can't check the brand because I'm out of the country this week. A couple of the local hardware stores carry them, but you certainly can't get them at Home Depot. These screws come in sizes 3/16, 1/4 inch and up, with lengths up to eight inches or so. They are very strong. They have a self-drilling point, a short threaded portion and a smooth shank. The heads are either flat or a large dome. They always use Torx drivers. These screws are much more expensive than lags, but they do not twist off.
