These cup hooks are half utility hook and half screw. Use them to hang cups, planters, feeders or other light goods from the bottom of shelves, in walls, or other wood structures. Aids in creating space in cabinets and keeping things organized or hanging from walls or ceilings. Easy to install by hand. Some applications may required pre-drilling. Brass plated.
Not for drywall! use in wood or aluminum. Drill pilot hole small enough to just start the tip of the threads into the material. I have used these cup hooks in aluminum and wood and they are strong and reliable. about 12 Oz max per hook.
