I love this product. Very solid and heavy feeling. It comes with 2 screws of different lengths. Neither of which was long enough for use on my bifold standard closet door. I ended up purchasing a screw from our local Home Depot store. #8 1 1/2". About $.30. *While at the store I checked out their selection of Crystal knobs and they had nothing that was as pretty or solid feeling. This was money well spent and I have since ordered 2 more for another set of doors.
