Expansion wall plug

The expansion wall plug is designed for fastening items to walls, ceilings, or floor structures. It consists of two wedges secured by a special washer.

As the screw is driven in, the plug expands within the hole. Thanks to the use of plastic, the wedges conform to the shape of the material and provide secure fastening in the hole.

The design also features ribs that limit pull-out.

Product features and types

The expansion wall plug consists of two parts. The non-expanding part preserves the soft surface layer of the material: when the screw is driven in, this element does not expand, so chipping is avoided. The expanding part has a smaller diameter than the screw, ensuring secure wedging after installation.

Main types:

• With nut;
• With wood screw;
• With nail;
• With machine screw;
• “Chapay” type.

Each variant differs in purpose and the types of material being fastened: hanging furniture items, profiles, brackets, and board insulation.
