This is a nice little product. Unfortunately, the length of the screw is not long enough for a practical application requiring a 10-20 pound hanging weight. It may not be that screw long enough to go through plaster or drywall and then an inch or more into a rack. The screw is only an inch long. You need to include a longer screw. A longer standard screw will not fit due to the hook clamp on the screw head. The included screw head has a flat, nail-like bottom. You cannot clamp the hook with a regular screw. I would even say it's a waste of money when a little more thought and pennies more would make it a five star product.
