Description: Size & Package - The hollow wall anchors screws includes 16 pcs of expansion nuts and 16 pcs of matching screws, ensuring sufficient quantity for various installation applications and providing a secure and durable fastening effect. The screw size is 12.5 x 8 x 34.5mm / 0.49 x 0.31 x 1.36 Inch (Head Dia. x Base Dia. x L), while the nut size is 18 x 6.6 x 21.5mm / 0.71 x 0.26 x 0.85 Inch (Head Dia. x Base Dia. x L) and the applicable thickness range is 0-5mm / 0-0.2 inch. Wide Application - The rivet nuts are suitable for most applications, especially for thin or hollow materials where traditional fasteners difficult to handle, such as aluminum alloy, steel pipe, iron sheet and acrylic plate, for hanging curtain rods, hollow doors, metal frames, wall cabinets, wall panels, coat racks, license plates and container labels, etc. Easy to Install - The petal nuts are designed for hand and air tools, and are simple to install. Use two wrenches/pliers, one to fix the rivet nut to prevent it from rotating after being inserted into the hole; the other to tighten the nut to fix it in place. Screw the screw into the nut and tighten until it is firmly pressed. Be careful to avoid over-tightening to prevent stripping. Note - The hollow wall anchors screws are made of carbon steel with high strength, rust-proof, corrosion-resistant, not easy to deform or break, can be firmly fixed to the plate, suitable for long-term use in various environments. It is recommended to select an appropriate tip and avoid the guide for optimal flange access. Petal-shaped Metal Nuts - The petal-shaped design of the nut allows the screw to grip the wall during expansion better, providing a more tightening effect, reducing slipping and effectively preventing loosening. The petal shape can also evenly distribute the clamping force and protect the fastened parts from damage.
