Universal expansion anchor bolt UNO 8 mm blue UNO-K-08

Expansion bolt UNO is a versatile fastening element that will be useful in many applications. A diameter of 8 mm and a universal design allow for solid anchoring in various building materials, both solid and hollow. This is an ideal solution for both professionals and DIY enthusiasts who value reliability and ease of installation.

Universal mounting in any substrate

The key feature of the UNO bolt is its ability to adapt to a variety of substrates. The reversed expansion ensures a secure setting in concrete, bricks (solid and perforated), aerated concrete, and even gypsum plasterboard and gypsum fiberboard. This means that one bolt can replace several different types, which greatly simplifies work and reduces costs. The short length (32 mm) makes it a good choice for thin walls, where standard bolts may be too long.

Stability and safety

The design of the UNO bolt has been carefully thought out for maximum stability and safety. Anti-rotation wings prevent the bolt from rotating during screwing, ensuring precise anchoring. The collar stabilizes the bolt and prevents it from slipping in the hole. The unique geometry guarantees optimal expansion and adhesion to the substrate, which translates into high load capacity.

Wide range of applications

The UNO bolt finds application in many construction and renovation areas:

• Mounting bathroom accessories (towel rails, shelves).
• Anchoring boilers and radiators.
• Mounting cabinets, brackets and wall brackets.
• Electrical installations – mounting electrical boxes and cables.
• Lighting installation.
• TV brackets on walls made of various materials.
• Suspended ceilings – mounting structural elements.

The recommended screw diameter is 4.5 - 6.0 mm, and the minimum hole depth is 42 mm. Remember to maintain a minimum substrate thickness (80 mm) and appropriate spacing between bolts (minimum spacing 64 mm) and from the edges (minimum distance 64 mm). UNO bolts are available in packs of 100 pieces weighing 0.15 kg.
