About this item
- Size & Package - The package includes 5 pieces of expansion nuts, ensuring sufficient quantity for various installation applications and providing a secure and durable fastening effect. The nut size is 18 x 8 x 22mm / 0.71 x 0.31 x 0.87 Inch (Head Dia. x Base Dia. x L) and the flange thickness is 2 mm / 0.08 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. Screw a hole matching the rivet nut's mounting hole size, insert the rivet nut, and use the riveting tool to secure the locking nut.
- Note - The jack nuts are made of 304 stainless 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.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
