Screw-in rounded shelf hooks

These screw in shelf hooks were designed to hold up to 25mm closet bars. They require countersink M3 tap screws of at least 6mm to tap into the surface you want. I used them in a homemade shelf in my bathroom closet to hold a bar that I can hook drying clothes and my baby bath tub. They are designed to hold some substantial weight, but the risk is yours, test beforehand! PETG only, PLA will creep and break over time.
