Four different times now when having my tires rotated one of the wheel studs on

What is your question?

Either side of the front have snapped. They have not been over torqued and have been hand not air gunned tightened. I have thought of using anti seize but read this is not a good idea, so now I'm left trying to locate durable after market lu studs it seems the OEM ones are the only weak point in an otherwise excellent car.
