Universal expansion anchor UNO 5mm with screw 3.5x30 mm, pack of 100 pcs. /100pcs/ UNO-05+330

Universal expansion anchor for various substrates

The UNO® expansion anchor with screw is a reliable solution for fastening in many building materials – both solid and hollow. Its universal geometry ensures stable anchoring even in substrates of low quality or irregular shapes. The complete set with a screw simplifies and speeds up installation, saving time and eliminating the need to search for the right fastening element.

Features and applications

The UNO anchor is particularly recommended for applications where versatility and secure fastening are required. It is suitable for:

• Mounting bathroom accessories, such as towel rails and shelves.
• Installation of electrical elements – flush-mounted boxes, trunking.
• Mounting radiators and heating system components.
• Finishing works, e.g. mounting skirting boards.
• Anchoring brackets, cabinets and other structural elements.
• Mounting in aerated concrete, solid and silicate bricks, and concrete.

Thanks to its special design, the UNO anchor also performs well in difficult conditions – in exploited substrates or with unknown structure. Anti-rotation wings prevent the anchor from rotating during screwing, and the stabilizing collar ensures optimal seating without risk of shifting. The short length of the anchor makes it ideal for thin walls and spaces with limited space.

Construction and materials

The UNO anchor is made of high-quality plastic, which guarantees its durability and resistance to mechanical damage. The set also includes a carbon steel screw with dimensions 3.5x30 mm, providing a solid connection between the fastened element and the substrate. Designed to work with a mounting hole diameter of 5 mm. This anchor works in concrete, solid and perforated bricks, and aerated concrete – it is a truly universal solution for professionals and DIY enthusiasts.
