Metal Wall Plugs for Hollow Walls M5x28mm Black 12Pcs

Size and Packaging - The hollow wall anchors include 12 expansion nuts and 12 assorted screws, providing a sufficient quantity for various installation applications and a secure and durable fixing effect. The screw size is 10 x 5 x 28mm / 0.39 x 0.2 x 1.1 inch (Head Dia x Base Dia x L), while the nut size is 14 x 4.3 x 19mm / 0.55 x 0.17 x 0.75 inch (Head Dia x Base Dia x L), and the applicable thickness range is 0-5mm / 0-0.2 inch.
Wide Application - Rivet nuts are suitable for most applications, especially for thin or hollow materials where traditional fasteners are difficult to handle, such as aluminum alloy, steel tubing, iron sheet, and acrylic sheet, for hanging curtain rods, hollow doors, metal frames, wall cabinets, wall panels, coat racks, license plates, container labels, etc.
Easy Installation - The Petal nuts are designed for use with both hand and pneumatic tools and are easy to install. Use two wrenches/pliers: one to secure the rivet nut to prevent it from rotating after insertion into the hole, and the other to tighten the nut to secure it in place. Screw the screw into the nut and tighten until it is firmly seated. Be careful not to overtighten to prevent stripping. Note: Hollow wall anchors are made of high-strength carbon steel, which is rust and corrosion resistant, will not deform or break easily, and can be firmly attached to the plate, making them suitable for long-term use in various environments. It is recommended to select a suitable drill bit and avoid using a guide for optimal access to the flange. Petal Metal Nuts - The petal design of the nut allows the screw to better grip the wall during expansion, providing an increased tightening effect, reducing slippage, and effectively preventing loosening. The petal shape can also evenly distribute the tightening force and protect the fastened parts from damage.
