No problems so far. good price too. The Home Depot (GRK brand) equivalent for a #10, 4-inch screw like this is $13.50 for a pack of 50, so you'll save about $4 if you buy the same quantity. Also, GRK screws are not coated at all. A star head is good too - the more I use my impact wrench, the more I hate Phillips head screws. They always come off eventually but I've had no problems with star washers I've bought recently, great screw at a good price.
