Screw doesn't start drilling or slips on the surface.
prob_01
Common root cause: Surface too hard, worn drill bit tip, or incorrect tool.
Step-by-step solution: Check if the surface is compatible (thin metal sheet, wood, drywall). Use a drill with good RPM and the correct bit. If the screw tip is damaged, use another.
💡 Pro tip: For harder surfaces, drill a smaller pilot hole with a standard drill bit before using the self-drilling screw.
📸 Evidence to provide support: Clear photo of the screw tip and the surface where you tried to drill.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Activate the warranty if, after using the screws on compatible materials and following the usage instructions, you notice the drill tip doesn't penetrate, the screw spins without fastening, or the screw material shows structural failures (e.g., breaks without excessive force), indicating a manufacturing defect.
