Dowels Fischer DUOPOWER Round, 3 cm length, 6 mm hole, pack of 100

Fischer DUOPOWER round dowels, pack of 100, each 3 cm long for a 6 mm drill hole. These universal plastic anchors are designed to work in a wide range of base materials, adapting automatically to solid and hollow substrates. The DUOPOWER concept combines three functional behaviours — folding, expanding and knotting — so a single dowel can provide secure fixing for general fastening tasks. Minimum drill depth required is 4 cm; the dowel delivers clear tactile feedback during screw installation to help ensure a reliable connection.

Advantages

The DUOPOWER round dowel adapts to different substrates and transfers load reliably through three mechanisms: folding in hollow materials, expanding in solid substrates and forming a knot in perforated or irregular bases. This versatile behaviour makes one dowel suitable for multiple applications, reducing the need to stock different anchor types. The compact 3 cm length and 6 mm drill size are suitable for common household and light-construction screws, and the pack of 100 supports multiple jobs or large installations.

Suitable for

• Fixing shelves, brackets and lightweight furniture to solid walls
• Anchoring fixtures to hollow block walls and partition systems
• Mounting electrical boxes, conduit clips and cable trays
• General fastening tasks in concrete, brick, aerated concrete and plastered surfaces

Key specifications

• Dowel length: 30 mm
• Recommended drill diameter: 6 mm
• Minimum drill depth: 40 mm
• Material: plastic two-component design providing folding, expanding and knotting functions
• Pack quantity: 100 pieces

How to use

Drill a 6 mm hole to a minimum depth of 40 mm, remove drilling dust, then insert the dowel flush with the surface. Choose a screw appropriate for the substrate and load; when tightening, the dowel will either expand, fold or form a knot depending on the base material. Tighten the screw until you feel firm resistance and the dowel gives clear feedback, avoiding over-tightening that could damage the anchor or the base material.

Usage recommendations

Use the DUOPOWER dowel with screws of suitable length so that the screw shank engages the anchor without bottoming out. For hollow or perforated materials, allow the dowel space to fold and verify anchorage with a test fixing. Do not use damaged dowels; replace any deformed anchors before installation.
