Frequently Asked Questions

Q: What surfaces do these suction cups with screw nuts work best on?

A: These suction cups are designed for smooth, non-porous surfaces including glass, acrylic panels, ceramic tiles, mirrors, polished metal, and car windows. They do not adhere well to rough, textured, or porous surfaces such as painted drywall or bare brick.

Q: What is the M6 screw nut used for?

A: The M6 screw nut embedded in each suction cup allows you to attach hooks, rods, bolts, or other M6-threaded accessories directly and securely. This gives you a much stronger and more stable mount compared to a plain suction cup with no hardware attachment point.

Q: Are these suction cups safe to use in wet areas like the bathroom or kitchen?

A: Yes! The PVC material is fully waterproof, making these suction cups ideal for damp environments such as bathrooms, showers, and kitchen backsplashes. Simply press firmly onto a clean, dry surface for the best hold.

Q: How do I remove the suction cups without damaging the surface?

A: To remove, gently lift the edge of the suction cup to let air in and break the seal, then pull it away from the surface. This releases the vacuum without leaving marks or damage on most surfaces.
